摘　　要：采用水雾化304不锈钢粉末与氮气雾化的高锰不锈钢粉末为原料,经混合、成形和高温真空烧结后,在不同温度下进行渗氮.结果表明:随着渗氮温度的升高,氮含量增加,抗弯强度增加.当w(N)>0.6%时,抗弯强度略有降低.材料的盐雾腐蚀等级随氮含量的增加而降低,硬度随氮含量的增加而增加.Using water atomized 304 stainless steel powders, and nitrogen atomized high manganese stainless steel powder as raw materials, a kind of stainless steel material with high nitrogen was prepared by mixing, form- ing and vacuum sintering at high temperature, and was further treated with nitrogen at different temperatures. The results showed that when the content of nitrogen was less than 0.6%wt,the bending strength of the material was increased with the increasing of nitriding temperature when the content of nitrogen was more than 0.6%wt, the bending strength was decreased slightly. The salt spray corrosion level was decreased,and the hardness was in- creased with the increase of the nitrogen content.
