借助OM和SEM研究和分析了正火温度对低合金铸钢摩擦磨损性能的影响。结果表明,正火后钢的组织为贝氏体和铁素体。随回火温度升高钢的磨损体积和磨损率增加,加载200 N时磨损体积及磨损率大于加载100 N的;磨损主要以氧化磨损、粘着磨损为主,同时伴有少量的磨粒磨损及微观切削。
The influence of normalizing temperature on the friction and wear properties of low alloyed cast steel was studied and analyzed by means of OM and SEM. The results show that the normalized steel is bainite and ferrite. With the increase of tempering temperature, the wear volume and wear rate of steel increase. The wear volume and wear rate are higher than that of 100 N when 200 N is loaded. Wear is mainly oxidative wear and adhesive wear, accompanied by a small amount of abrasive wear and Micro-cutting.
