In addition to RF- and DC-sources, pulsedplasma sources are gaining increased attention. This interest is driven by the wish ofdepositing coatings with superior properties as compared to those deposited by conven-tional techniques. One prominent example of coatings that are significantly enhancedby the usage of pulsed plasmas is alumina. Although crystalline α-alumina can be de-posited by thermal CVD at temperatures above 1000℃ for two decades, no process forthe deposition of crystalline alumina on heat sensitive substrates like tempered steelsat low temperatures is commercially available up to now. In this paper, the depositionof alumina films from gaseous mixtures of AlCls-N2-H2-Ar in a bipolar pulsed glowdischarge at about 500℃ is reported. Special attention was paid on the correlation be-tween plasma characteristics and film properties. The measurements revealed that theproperties of the resulting coatings were significantly influenced by the characteristicsof the power supply. Depending on the gas composition and the plasma parameters,alumina films with high hardness and good adhesion were deposited.","authors":[{"authorName":"O.Kyrylov","id":"6e06d95f-6277-4dc3-93cf-850d1af089dc","originalAuthorName":"O.Kyrylov"},{"authorName":" R.Cremer","id":"06166a8a-eb83-4e89-8acc-9cfe09244e32","originalAuthorName":" R.Cremer"},{"authorName":" D.Neuschütz","id":"eb32a799-f9f6-4e86-a149-fd194e4f7b75","originalAuthorName":" D.Neuschütz"}],"categoryName":"|","doi":"","fpage":"1","id":"aed91727-50df-4115-afdc-2a470fa073ac","issue":"1","journal":{"abbrevTitle":"JSXBYWB","coverImgSrc":"journal/img/cover/amse.jpg","id":"49","issnPpub":"1006-7191","publisherId":"JSXBYWB","title":"金属学报(英文版)"},"keywords":[{"id":"c7dd3e08-ae21-49a4-abf2-5cd3f1cb0e3f","keyword":"alumina","originalKeyword":"alumina"},{"id":"920f4f55-37ef-4c77-a1dc-f7247fb7275e","keyword":"null","originalKeyword":"null"},{"id":"a22cce7e-88d2-4886-bb1f-be871261f7d9","keyword":"null","originalKeyword":"null"},{"id":"7a825134-a8f5-4f23-89e5-9791e5183bb8","keyword":"null","originalKeyword":"null"}],"language":"en","publisherId":"1006-7191_2002_1_24","title":"BIPOLAR PULSED PECVD OF ALUMINA HARD COATINGS","volume":"15","year":"2002"},{"abstractinfo":"The phenomenon of the precursor film in a metal-ceramics wetting system was investigated using tin-based active solder (active element: Ti, Zr, Nb, V, Hf or Ta, the third element Ni, Cu, Ag, In or Al) wetting on the ceramics (sialon, mullite, barium titanate alumina and ZTA-SiC). The results show that the formation of a precursor film in the wetting system is dependent on the following factors. (1) The active metal: the presence of titanium, zirconium or hafnium in the solders induced the formation of a precursor film, but niobium, vanadium and tantalum did not. (2) Temperature: a precursor film will not form unless the critical wetting temperature is reached, while a weak film will form during a second wetting at higher temperature. (3) Ceramics: under the same wetting conditions for Sn-4Ti solder, a precursor film forms on the surface of sialon, ZTA-SiC, and red alumina, but not on white alumina, mullite or barium titanate. (4) The third element; small amounts of nickel (1-3 at %), copper (5 at %), or silver (5 at %) in Sn-5 at % Ti solder will enhance the precursor film. On the other hand, small amounts of Al (5 at %) will completely inhibit the occurrence of precursor film. SEM observation reveals the precursor film to be mainly composed of a continuous film with segregated active metal and some small tin islands on the film. Its thickness is several micrometres, similar to that of the interfacial reaction layer between the solder and the ceramic. Two early theories for the formation of a precursor film, surface diffusion and evaporation-condensation, cannot explain the above phenomenon very well. A new model of rapid absorption then film overflow is proposed here for the first time and some problems with the model are also discussed.","authors":[],"categoryName":"|","doi":"","fpage":"1019","id":"aa2df350-957d-497d-9fb1-ba2419e29ea5","issue":"4","journal":{"abbrevTitle":"JOMS","id":"d451b714-34b6-45ff-beb7-4cb8e1a8bb9d","issnPpub":"0022-2461","publisherId":"JOMS","title":"Journal of Materials Science"},"keywords":[{"id":"c7bf9dfc-ce6b-40a4-9ed4-e5e4f6bcd60c","keyword":"brazing filler metal;joints;solids","originalKeyword":"brazing filler metal;joints;solids"}],"language":"en","publisherId":"0022-2461_1993_4_1","title":"PRECURSOR FILM OF TIN-BASED ACTIVE SOLDER WETTING ON CERAMICS","volume":"28","year":"1993"},{"abstractinfo":"High purity alumina ceramics (99% Al2O3) was implanted by copper ion and titanium ion in a metal vapour vacuum arc (MEVVA) implanter, respectively.
