摘　　要：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℃范围内进行奥氏体离子氮碳共渗后，其耐磨性和抗咬合性以６３０℃处理时为最佳，６６０℃最差，而５７０—６００℃介于二者之间，通过适当提高共渗温度在提高渗速从而缩短共渗时间的同时，可以提高耐磨损性能。Studies of the wear resistance and anti-adhesion of 20# and 45# steel formed in austenitic ion-nitrocarburising and comparisons to the general ion-nitrocarburising are presented in this thesis. The experiment shows that austenitic ion-nitrocarburising can be carried out at 570-700℃, its wear resistance and anti-adhesion is the best at 630℃, the worst at 660℃ and the mediate at 570-600℃. The wear behaviour can be improved by raising processing temperature properly and speeding up the process, future shortening processing time.
