摘　　要：本文对ＦｅＭｎＳｉＣｒＮｉ形状记忆合金耐腐蚀性能进行研究。合金的电化学极化曲线表明：与３０４、３１６不锈钢相比，具有较低的腐蚀电流，较大的阴极极化曲线斜率。腐蚀失重实验结果表明：该合金在碱性介质中耐腐蚀性能是３０４、３１６不锈钢的４～５倍。Corrosion resistance of FeMnSiCrNi alloy was studied. Loss weight showed that corrosion resistance of FeMnSiCrNi alloy was better than that of 316 and 304 stainless steels,which was 4～5 times that of 316 and 304. Anodic and cathodic polarization measurments were conducted separately for different type of alloy. Ecorr of FeMnSiCrNi was more positive value for all alloys. Icorr of FeMnSiCrNi was smaller than that of 316 and 304 stainless steels.
