摘要
添加了Ｍｏ和Ｃｕ的铬锰氮不锈钢，合金钝化膜更加完整，且稳定性高。钝化膜主要由Ｆｅ、Ｃｒ和Ｍｏ的含水氧化物组成，添加Ｍｏ和Ｃｕ的合金钝化膜有Ｃｒ、Ｍｏ和Ｃｕ的富集，且Ｃｒ／Ｆｅ的比值高，膜薄却致密，耐蚀性能好。它具有优于１８—８和１Ｃｒ１８Ｎｉ１２Ｍｏ２Ｔｉ钢的耐均匀腐蚀。
The complete, stable alloying passive films are achieved through the addition of Mo and Cu into the Cr-Mn-N cast stainless steel,the passive films mainly consist of Fe,Cr and Mo oxides which appears to be enrichment of Cr,Mo and Cu elements,Cr/Fe ratio is high,the passive films are thin and compact, the uniform corrosion,pitting corrosion and intergranular corrosion of the Cr-Mo-N cast stainless steel are superior to that of 1Cr18Ni12Mo2Ti and 18-8 cast stainless steel.
