摘　　要：在生产过程中采用改性纳米SiC粉体对低碳马氏体不锈钢进行了处理,研究了改性纳米SiC粉体对低碳马氏体不锈钢的金相组织和耐腐蚀性能的影响。结果表明:经改性纳米SiC粉体处理后的马氏体不锈钢,在NaCl溶液和FeCl3溶液中的抗腐蚀性能均有明显的提高,且经工艺三处理过的试样,其抗腐蚀能力更强。The low-carbon martensitic stainless steel was reinforced by surface modified SiC nano-powders. The effect of adding process of SiC nano-powders on the microstructure and corrosion resistance of low-carbon martensitic stainless steel was investigated. The results indicate that the anti-corrosion capacity in NaC1 solution and FeCI3 solution of the reinforced martensitic stainless steel increases with two adding processes. And the samples with the third adding process has the best anti-corrosion capacity.
