EROSION AND EROSION-CORROSION BEHAVIOR OF STAINLESS STEELS IN DUAL-PHASE FLUID
不锈钢在液固双相流中的冲蚀腐蚀行为

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.
