摘要: <正> 氮离子注入用于提高金属材料的耐磨性、耐疲劳性能,研究较多,工程上已有应用实例。用于耐水溶液腐蚀方面研究得较少,仅见对纯铁和碳钢耐蚀改性的理论研究。本文介绍用氮离子注入对1Cr18Ni9Ti不锈钢进行表面改性以提高在硝酸磷肥溶液中的耐蚀性能,通过表面成份及组织结构分析探讨耐蚀改性的机理。

Abstract：The modification of corrosion resistance of 1Cr18Ni9Ti stainless steel in Phosphonitrogen by nitrogen implantation was investigated by electrochemical measurements, TEM and AES. The results show that the open potential of implanted specimens shifts towards positive direction and that their corrosion current measured by weak polarization technique decreases. The passive current density is greatly affeted by implantation dose. The best modification effect has been obtained at dosage of 1×10~(17) N~+/cm~2 when an amorphous structure of the formation of nitride precipitate,excessive implantation is detrimental to corrosion resistance of the stainless steel.
