采用旋转圆筒电极装置研究了１Ｃｒ１３（铁素体）、３１６Ｌ（奥氏体）、０Ｃｒ１４Ｎｉ５Ｍｏ（马氏体）及ＣＤ－４ＭＣｕ（α＋γ双相）等不锈钢在不同流速水砂双相流中的冲蚀及ＮａＣｌ（＋Ｈ２ＳＯ４）砂浆中的冲蚀腐蚀行为，用ＳＥＭ观察了冲蚀（腐蚀）后材料表面形貌，并测定了样品表层硬度变化。结果表明双相不锈钢ＣＤ－４ＭＣｕ因其较强的加工硬化能力而具有优良的抗冲蚀腐蚀性能。
Emion and erosion-cornxion behaviors of several stainless steels, such as 1Cr13 (fenitic), 316L (austenitic) , OG14Nim (martensitic) and CD4MCu ( a + Y duplex), were studied by using rotating cylinder electmlyzer apparatus. All experiments were conducted in slurry containing synthetic water with or without NaCl( + Hz=) at different fluid velocity. The mrpholcgies of steels after emion or erosion-amwion were observed. The variation of surface rnicmhardness and the hardness distribution in sub-surface were measured as well. The results s M that CD4MCu ha. higher carrrsion mion resistance because of its excellent passibility of defomtion strengthening.
