为了解决传统奥氏体不锈钢耐磨性较差的问题,本文设计了一种新型的Fe-Mn-Si-Cr-Ni-C奥氏体不锈钢,并研究了其耐磨性能和耐腐蚀性能.研究表明:Fe-Mn-Si-Cr-Ni-C奥氏体不锈钢在干摩擦和油润滑条件下均具有比1Cr18Ni9Ti奥氏体不锈钢更好的耐磨性,在NaCl中耐蚀性不如1Cr18Ni9Ti不锈钢,但在NaOH中优于1Cr18Ni9Ti不锈钢.Fe-Mn-Si-Cr-Ni-C奥氏体不锈钢应力作用下发生的应力诱发γ→ε马氏体相变是其具有较高耐磨性的原因.
In order to solve the problem of poor wear resistance of traditional austenitic stainless steel, a new type of Fe-Mn-Si-Cr-Ni-C austenitic stainless steel was designed and its wear resistance and corrosion resistance were studied. The results show that the wear resistance of Fe-Mn-Si-Cr-Ni-C austenitic stainless steels is better than that of 1Cr18Ni9Ti austenitic stainless steels under both dry and oil lubricated conditions, while the corrosion resistance in NaCl is inferior to that of 1Cr18Ni9Ti stainless steels , But superior to 1Cr18Ni9Ti stainless steel in NaOH.The stress induced γ → ε martensitic transformation under the stress of Fe-Mn-Si-Cr-Ni-C austenitic stainless steel is the reason of its high wear resistance .
