摘要
通过腐蚀重量法实验及电化学测试，研究了Ｆｅ－Ｍｎ－Ｓｉ－Ｃｒ形状记忆合金的耐腐蚀性能，并与Ｆｅ－Ｍｎ－Ｓｉ形状记忆合金及１８－８铬镍不锈钢的耐腐蚀性能作了比较。结果表明，Ｆｅ－Ｍｎ－Ｓｉ－Ｃｒ合金的耐腐蚀性能明显高于Ｆｅ－Ｍｎ－Ｓｉ合金，在Ｆｅ－Ｍｎ－Ｓｉ－Ｃｒ合金中随着铬含量的增加，其耐腐蚀性能也相应提高。
The crrosion resistance of Fe-Mn-Si-Cr shape memory alloy was studied through corrosion weight-loss and electrochemistry experiments,and com-pared with that of Fe-Mn-Si shape memory alloy and 18-8 Cr-Ni stainless steel. The results show that the corrosion resistance of Fe- Mn- Si-Cr alloy is obviously higher than that of Fe-Mn-Si alloy.The corrosion resistance of Fe- Mn- Si-Cr alloy correspondingly increases with increasing of Cr content.
