摘要
研究了不锈钢粉末表面化学镀铜对烧结不锈钢组织和耐蚀性的影响 .实验表明 ,以化学包覆不锈钢粉的形式加入 1～ 5wt%的铜 ,在 115 0℃液相烧结时 ,在烧结不锈钢中 ,铜元素分布的均匀性以及烧结体的密度比机械混合方式加入铜都有很大提高 ;同时通过电化学实验表明 ,化学镀铜方式有利于提高不锈钢烧结体的耐蚀性。
In this work, effect of Cu-electroless plating on stainless steel powder on microstructure and corrosion behaviour of sintered stainless steel was investigated. Stainless steel powder containing Cu (1-5wt%) was prepared using the electroless Cu-plating methods. It was found that Cu-electroless plating of 1-5wt% diffuses into stainless steel matrix more uniform and renders a less porous surface with isolated pores than that of the sintered stainless steel fabricated by mixing Cu powder with stainless steel powder, thus improving the density of sintered stainless steel. Potentiodynamic polarization measurements indicate that Cu-electroless plating of 1-5wt% improves the corrosion resistance of sintered stainless steel.
