通过对缸套实际使用情况调查证明,其失效原因主要为磨粒磨损,因此对如何提高缸套的耐磨性已是国内外研究的重要课题。目前广为使用的是灰铸铁淬火缸套,一般生产单位仅凭淬火层硬度去评价质量,却往往忽视组织形态对耐磨性的影响。本文目的在于通过实验找出组织形 Through the actual use of cylinder liner survey proved that the main cause of failure is abrasive wear, so how to improve the wear resistance of cylinder liner is an important issue at home and abroad. Currently widely used is the gray cast iron cylinder liner, the general production unit hardness alone to evaluate the quality of quenching layer, but often ignore the impact of organizational morphology on the wear resistance. The purpose of this paper is to find out the shape of the experiment through experiments
