１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢的表面Ｃｏ基材料的激光熔覆，在熔覆层表面形成了致密的微结构．基体与熔覆层间的热影响区内，基体元素的固溶度明显增加，位错能降低，在热影响区还发现了孪晶产生．根据Ｍｓｓｂａｕｅｒ谱研究确认有多种Ｆｅ、Ｃ固溶相的存在．

The microstrueture of laser melted Co base allog was studied.The results show that solid solubility was inereased and twin crystal was found in heat effect area. A lot of Fe,C solid solubility were deduees from results of Mssbauer spectrum.The fact that surface properies was impro...
