本文研究了几种铸铁的耐磨性能,发现可淬硬低合金铸铁强度高,耐磨性优异,少量形状适当的合金渗碳体 的存在对提高铸铁的耐磨性非常有益,认为可淬硬低合金铸铁是摩托车凸轮轴材质的适宜选择。
In this paper, we study the wear resistance of several cast irons. We found that the hardenable low alloy cast iron has the advantages of high strength and excellent wear resistance. The presence of a small amount of suitable alloy cementite is very beneficial to improve the wear resistance of cast iron. Low alloy cast iron is a suitable choice of motorcycle camshaft material.
