Abstract
The effect of different normalizing temperature on the friction and wear properties of low alloy wear-resistant cast steel was investigated with the help of OM and SEM.Dry friction and wear experiment was carried out on an MMS-2A friction and wear testing machine with different loads,100 N and 200 N respectively.The test results show that the microstructure consists of bainite and ferrite after normalizing.The wear volume and wear rates increase with the increase of tempering temperature,the sample with the load of 200 N has a higher wear volume and wear rate.The wear form of the sample is mainly oxidation wear,adhesive wear,and at the same time accompanied by a small amount of abrasive wear and micro cutting.关键词
