摘要
研究 2 0钢、45钢经奥氏体离子氮碳共渗后的耐磨性和抗咬合性 ,并与普通离子氮碳共渗后的作了比较 ,试验表明 :在 5 70～ 70 0℃范围内进行离子氮碳共渗后 ,其耐磨性和抗咬合性以 6 30℃处理时为最佳 ,6 6 0℃处理时最差 ,而 5 70～ 6 0 0℃处理时则介于两者之间 ,通过适当提高共渗温度 ,再提高渗速 ,从而缩短共渗时间的同时 ,可以提高耐磨损性能。
The paper analyzes the wear resistance and anti-adhesion of 20 and 45 steel formed in austenitic ion-nitrocarburising and comparisons to the general ion-nitrocarburising. The experiment shows that austenitization -nitrocarburising can be carried out at 590～700℃, its wear resistance and anti-adhesion is the best at 630℃,the worst at 660℃ and anti-adhesion is the best at 630℃,the worst at 660℃ and the mediate at 570～600℃. With the help of raising processing temperature properly and speeding up the process the wear behavior can be improved.
