摘要
研究了ｃｆ５３钢的淬透性，以及接触疲劳性能．测定了Ｐ－Ｎ和Ｐ－Ｓ－Ｎ曲线．扫描电镜分析表明，ｃｆ５３钢接触疲劳损伤是由于表面裂纹的萌生与扩展，直至剥落．摩擦力与τ４５的合力是表面裂纹萌生的驱动力．
The hardenability and contact fatigue property of53 is studied. The P-N and P-S-N curves are measured with the method of materials-rolling contact fatigue test. The contact fatigue failure of of53 is by reason of initiation and propagation of surface cracks. The Resultant of friction and τ45 is the driving force of surface cracks.
