Abstract : 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
文摘:研究20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570 700范围内进行离子氮碳共渗后，其耐磨性和抗咬合性以630处理时为最佳， 660处理时最差，而570 600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。
