摘要
Abstract
The microstructure and hardness of different parts of the Q460 steel were analyzed, the friction and wear test were carried out by using ring block type and pin disk sliding wear testing.The results show that the microstructure of edge and core of Q460 steel spindle are ferrite and pearlite, the microstructure of center is relatively large, and the average hardness is relatively low;Under the condition of ring block sliding wear test, with the increase of loading load, the wear loss and wear rate of Q460 steel under the condition of no lubrication and oil lubrication are gradually increasing, and when the load is same, the wear loss and wear rate under no lubrication condition are higher than that under the lubrication condition.Under the test condition of disc sliding wear, with the increase of load, the abrasion depth and wear rate of Q460 steel are gradually increasing with the increase of load.When the load is 20 N, the wear of Q460 steel is mainly fatigue wear and abrasive wear.When the load increases to 40 N, the wear form of Q460 steel is mainly fatigue wear.关键词
