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鋼、 45鋼經(jīng)奧氏體離子氮碳共滲后的耐磨性和抗咬合性,并與普通離子氮碳共滲后的作了比較,試驗(yàn)表明:在570 700范圍內(nèi)進(jìn)行離子氮碳共滲后,其耐磨性和抗咬合性以630處理時(shí)為最佳, 660處理時(shí)最差,而570 600處理時(shí)則介于兩者之間,通過適當(dāng)提高共滲溫度,再提高滲速,從而縮短共滲時(shí)間的同時(shí),可以提高耐磨損性能。
