摘要: <正> 一、前言激光表面合金化是一种很有前途的表面改性技术,它通过改变金属表面的化学成份,从而改善其电化学行为。Si是改善孔蚀特性的有效合金组分,含Si4.45%wt的Cr18Ni8不锈钢的耐孔蚀性能大约比304不锈钢好20倍。采用激光表面合金化以形成FeCrNiSi表面合金在国内、外至今未见报导。本工作采用激光表面合金化技术对低合金钢进行Cr-Ni-Si表面合金化,研究激光处理工艺条件和合金成份对耐蚀性能的影响。

Abstract：Laser surface alloying is an effective surface modification technique to improve corrosion resistance of metallic materials.In this paper laser sutface Cr-Ni-Si alloying on low alloy steel has been investigated and the effect of technological conditions of laser treatment and alloying composition on the corrosion resistance of surface alloy possessing uniform distribution of Cr,Ni and Si is diseussed.The experimental results indicated that the addition of silicon can remarkably improve the pitting resistance of the surface alloy.The mechanism of improved pitting resistance by silicon is that a protective film enriched with silicon has been formed on the surface.
