However, it is difficult to coat aluminum alloy on a bulky steel substrate without sufficient preheating, because a rapidly solidified layer containing gas babbles is formed on a substrate surface. A variety of iron-aluminides are also formed at the interface of a steel and aluminum hot-dip coating system, which is the main difficulty in joining of steel with aluminum. Ultrasonic vibration was applied to a steel substrate during hot-dip coating of aluminum alloy to control a rapidly solidified layer and a brittle reaction layer. Hot dipping of columnar steel substrates into molten aluminum alloy (Al-2.7 mass fraction Si-4.6 mass fraction Sn) was carried out through the use of a Langevin oscillator with resonant frequency of 19.5 kHz. The application of ultrasonic vibration is quite effective to control a rapidly solidified layer and a surface oxide layer from a substrate surface by the sonocapillary effect based on a cavitation phenomenon, so that the intimate contact is achieved at the beginning of hot-dip coating. The application of ultrasonic vibration to hot-dipping is effective to control a reaction layer with less than 5 μm in thickness. An impact test exhibits that the good adhesive strength is approved in hot-dipped aluminum coatings with a thin reaction layer of approximately 5 μm.","authors":[{"authorName":"Y.Tsunekawa","id":"50f89d94-599e-4557-900d-c4fdd12c1d58","originalAuthorName":"Y.Tsunekawa"},{"authorName":" S.Tamura","id":"5b528ae0-05f3-4561-8b80-5d25c4f9ad67","originalAuthorName":" S.Tamura"},{"authorName":" M.Okumiya","id":"055471ac-90ef-42b5-9782-78f2e901841e","originalAuthorName":" M.Okumiya"},{"authorName":" N.Ishihara","id":"27b9e1cd-b896-4c7d-bb79-e635d237fc8a","originalAuthorName":" N.Ishihara"}],"categoryName":"|","doi":"","fpage":"41","id":"07a0cc43-3562-40c0-a99b-11daa90e94b2","issue":"1","journal":{"abbrevTitle":"CLKXJSY","coverImgSrc":"journal/img/cover/JMST.jpg","id":"11","issnPpub":"1005-0302 ","publisherId":"CLKXJSY","title":"材料科学技术(英文)"},"keywords":[{"id":"602e6857-3fd8-40a9-aaed-b984ef38f914","keyword":"Ultrasonic vibration","originalKeyword":"Ultrasonic vibration"},{"id":"b69ea1f3-da13-4cd2-baf5-0e1a9fa9f014","keyword":"null","originalKeyword":"null"},{"id":"1488c3be-41d2-4338-b29c-839c20b057f9","keyword":"null","originalKeyword":"null"},{"id":"d449c5a0-4b87-4438-85b7-33d9a238d7f8","keyword":"null","originalKeyword":"null"}],"language":"en","publisherId":"1005-0302_2008_1_22","title":"Hot-Dip Coating of Lead-free Aluminum on Steel Substrates with Ultrasonic Vibration","volume":"24","year":"2008"},{"abstractinfo":"In hot-dip galvanizing process, air jet wiping control is so crucial to decide the coating thickness and uniformity of the zinc layer on the steel strip. The mathematical models developed predict the zinc coating thickness as a function of pressure and shear stress. The required pressure and shear stress profile on the strip surface were calculated using regression analysis, and carried out using numerical simulation as FLUENT, a finite element analysis software. The influences of the outlet pressure, the nozzle to strip distance, the slot opening, the edge baffle plate, as well as the tilting angle of air knife were discussed. Combining with these results and regression analysis on the practical data, four first-order polynomial multi-parameter models were established for different targeted coating thicknesses with better regression coefficients. The validated model was used to carry out sensitivity analysis to determine the favorable controlling regime for the air jet wiping process.","authors":[{"authorName":"ZHANG Yan","id":"6b403d85-4de6-4a2a-ae37-f5ddc5170d9d","originalAuthorName":"ZHANG Yan"},{"authorName":"","id":"9236669d-9b7e-414c-8945-68b54df140bf","originalAuthorName":""},{"authorName":"CUI Qi-peng","id":"5cdde230-cb84-4cc4-857d-ecbc5bb87be2","originalAuthorName":"CUI Qi-peng"},{"authorName":"SHAO Fu-qun","id":"d7c811bb-1bb3-4085-b13d-1d1eee64b685","originalAuthorName":"SHAO Fu-qun"},{"authorName":"WANG Jun-sheng","id":"31e395f5-9c14-4d50-a98c-3827317b28dc","originalAuthorName":"WANG Jun-sheng"},{"authorName":"ZHAO Hong-yang","id":"b5100571-4a70-4abc-b137-da6012f72c8e","originalAuthorName":"ZHAO Hong-yang"}],"categoryName":"|","doi":"","fpage":"70","id":"b220bad9-d401-49a6-97b9-28976dbf76d6","issue":"6","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"8b3b88e0-052c-42f2-a599-1512efbd8ebe","keyword":"hot-dip galvanizing ","originalKeyword":"hot-dip galvanizing "},{"id":"4384c134-de1f-4858-a39a-559e9ad56e08","keyword":" air knife ","originalKeyword":" air knife "},{"id":"21ebec0f-e861-4e06-86a8-0d7cca1af512","keyword":" air jet wiping ","originalKeyword":" air jet wiping "},{"id":"0740247d-6731-4880-aea3-b49d1b195765","keyword":" numerical simulation ","originalKeyword":" numerical simulation "},{"id":"0cc17623-f2c8-46b7-af95-6107935a401b","keyword":" coating thickness","originalKeyword":" coating thickness"}],"language":"en","publisherId":"1006-706X_2012_6_2","title":"Influence of Air-Knife Wiping on Coating Thickness in Hot-Dip Galvanizing","volume":"19","year":"2012"},{"abstractinfo":"While the thick growth of intermediate phase layers generally benefits the corrosion resistance of galvanized steels, it is unfavourable from the standpoints of mechanical integrity and economics. The present study investigates the role of nickel chloride-base fluxes, in relation to the typical zinc-ammonium chloride flux, in the reduction of galvanized coatings' thickness and the effect on coatings' morphology and compositions. The investigation of pretreated galvanized steel specimens hot-dipped for various durations has verified that nickel chloride fluxes influence the growth rate of the zeta interlayer. This results in the overall-reduction of the coating thickness by as much as two times compared to those prepared with the conventional flux. Nickel from the fluxes gradually diffuse away from the substrate's surface, and hence the initial concentration of the nickel salts along with the hot-dip duration need to be controlled appropriately for effective use of nickel chloride-base fluxes in the galvanizing process.","authors":[{"authorName":"null","id":"5ddb0399-1bac-439f-98e9-ca715e9259d7","originalAuthorName":"null"},{"authorName":"null","id":"0e05bcfa-f9fb-45a7-b699-a60791c29cf6","originalAuthorName":"null"},{"authorName":"null","id":"4f5c1cbf-0c29-4891-abf4-77530c8bd9d4","originalAuthorName":"null"}],"categoryName":"|","doi":"","fpage":"74","id":"0842260d-71b0-4f9c-9732-1a7920c581d2","issue":"8","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"58826219-98b5-4cfa-91c1-12c2f0b5bf68","keyword":"galvanization;zinc;nickel;flux;corrosion protection","originalKeyword":"galvanization;zinc;nickel;flux;corrosion protection"}],"language":"en","publisherId":"1006-706X_2010_8_8","title":"Effect of NiCl2-Base Fluxes on Interfacial Layer Formation of Hot-Dip Galvanized Steels","volume":"17","year":"2010"},{"abstractinfo":"A TiAl3-rich coating was developed by hot-dip aluminizing method and subsequent interdiffusion treatment on Ti-6.5Al-1Mo-1V-2Zr (mass %) alloy for high temperature resistance. Interrupted oxidation at temperatures from 973 to 1173 K and isothermal oxidation at temperatures from 923 to 1073 K of the TiAl3-rich coating were conducted. The coating markedly decreased the oxidation rate in comparison with the substrate alloy at 1073 K and lower during the interrupted oxidation, and a layered structure of Al2O3/TiAl3/TiAl2/TiAl/alloy from the outside to the inside formed after oxidation at 973 K without changing the main body of the TiAl3-rich coating. The oxidation kinetics followed parabolic relations during the stable state stage of the isothermal oxidation; the activation energy for oxidation of the coating was calculated as 323 kJ mol(-1). The hot-dip aluminizing coating provided high protectiveness for the Ti-6.5Al-1Mo-1V-2Zr alloy at 973 K and lower.

The analysis was based on the boundary element methods (BEMs) coupled with Newton-Raphson iterative technique to treat the nonlinear boundary conditions, which were determined by the experimental polarization curves. Results showed that galvanic current density concentrates on the boundary of steel substrate and zinc coating, and the sacrificial protection of zinc coating to steel substrate results in overprotection of steel cathode. Not only oxygen reduction but also hydrogen reduction could occur as cathode reactions, which probably led up to the adsorption and absorption of hydrogen atoms. Flat galvanized steel tensile sample shows a brittle behavior similar to hydrogen embrittlement according to the SSRT (show strain rate test) in seawater.","authors":[{"authorName":"Xiao Tang","id":"bf5d5213-1086-44cf-9b64-5df17ce7192e","originalAuthorName":"Xiao Tang"}],"categoryName":"|","doi":"","fpage":"194","id":"9cc103d0-da82-4752-9785-eb5d9b37547a","issue":"2","journal":{"abbrevTitle":"CLKXJSY","coverImgSrc":"journal/img/cover/JMST.jpg","id":"11","issnPpub":"1005-0302 ","publisherId":"CLKXJSY","title":"材料科学技术(英文)"},"keywords":[{"id":"c1b5a6a3-576c-465c-9a83-33b5b5b7fcf7","keyword":"Galvanic corrosion","originalKeyword":"Galvanic corrosion"},{"id":"3ec548dc-62ff-422e-9fa5-7d8bdf32d274","keyword":"null","originalKeyword":"null"},{"id":"3178ed58-9c14-4bc4-b31a-5149bc71f85c","keyword":"null","originalKeyword":"null"},{"id":"e96e0fc0-b93d-41ee-971c-803f5d981aac","keyword":"null","originalKeyword":"null"},{"id":"260b7f25-0424-4c8e-b380-fed1480bf927","keyword":"null","originalKeyword":"null"}],"language":"en","publisherId":"1005-0302_2009_2_16","title":"Boundary Element Method (BEM) Analysis for Galvanic Corrosion of Hot Dip Galvanized Steel Immersed in Seawater","volume":"25","year":"2009"},{"abstractinfo":"通过对纯锌镀层(GI)、5%Al-Zn合金镀层(GF)以及55%Al-Zn合金镀层(GL)这三种不同镀层产品进行杯突试验,以及用扫描电子显微镜对变形后镀层表面形态进行观察,得出了镀层的抗加工成形性的区别;在0.02mol/L NaCl溶液中,用电化学测量系统测定了三种镀层在不同杯突变形量条件下的线性极化电阻。结果表明,在相同变形情况下,对GI镀层耐腐蚀性能影响较小,而对GF及GL镀层的耐腐蚀性能影响较大。","authors":[{"authorName":"李黎","id":"748b6326-fa51-43d8-9c34-ca68d03422d9","originalAuthorName":"李黎"}],"categoryName":"|","doi":"","fpage":"5","id":"75a434f5-45bb-465c-85d1-28f84d68b41e","issue":"1","journal":{"abbrevTitle":"WLCS","coverImgSrc":"journal/img/cover/WLCS.jpg","id":"64","issnPpub":"1001-0777","publisherId":"WLCS","title":"物理测试"},"keywords":[{"id":"a3a473af-9492-4b38-b6c4-147f7ce03668","keyword":"杯突试验","originalKeyword":"杯突试验"},{"id":"d4be8038-0c7d-43c4-985c-bd63a3d2c9a9","keyword":"hot-dip Zinc","originalKeyword":"hot-dip Zinc"},{"id":"271a22b3-2d17-45f6-9eef-15c696fbe1d3","keyword":"0.02mol/L NaCl solution","originalKeyword":"0.02mol/L NaCl solution"},{"id":"6bd6f0e0-106b-4649-bd29-52d7fe15bd67","keyword":"polarization resistance","originalKeyword":"polarization resistance"},{"id":"2ad3e17e-2ce5-41d2-a7ab-d7ca5c47b152","keyword":"corrosion resistance","originalKeyword":"corrosion resistance"}],"language":"zh","publisherId":"1001-0777_2011_1_6","title":"杯突变形对锌合金镀层耐腐蚀性能的影响","volume":"29","year":"2011"},{"abstractinfo":"","authors":[{"authorName":"","id":"1ea2dace-82db-4079-9c3c-65f458128bd1","originalAuthorName":""},{"authorName":"","id":"612221f8-ca6d-42c9-bc19-40ee3f942d2e","originalAuthorName":""},{"authorName":"","id":"08f499c2-4a8b-4496-9860-1d340113dfaa","originalAuthorName":""}],"doi":"","fpage":"55","id":"1cc02507-8771-4ec4-aa2e-6709ee77a566","issue":"1","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"a2b2e410-aecd-40ba-a4f4-b54cc1f8605d","keyword":"","originalKeyword":""}],"language":"zh","publisherId":"gtyjxb-e200301012","title":"Hot-Dip Galvanized Sheet Production and Application","volume":"10","year":"2003"},{"abstractinfo":"The corrosion behavior of hot dip galvanized steel\npretreated with bis-[triethoxy-\\linebreak\\noindent silylpropyl]\ntetrasulfide (BTESPT) modified with alumina particles was studied.\nThe corrosion resistance of the passiving films was evaluated by\nTafel polarization curve and electrochemical impedance spectroscopy.\nThe films formed on the galvanized steel substrate were\ncharacterized by Fourier transform infrared spectroscopy and energy\ndispersive X-ray spectrometry.
