摘要: 对离子渗硫层的接触疲劳性能进行了研究。将调质处理的45钢进行低温离子渗硫处理后,在JP-52接触疲劳试验机上测定了渗硫层的疲劳寿命,表明其疲劳寿命比未渗硫处理的提高一倍左右。从接触应力、润滑介质、表面缺陷和表面粗糙度等几个方面分析了渗硫层对接触疲劳性能的影响。

Abstract: The contact fatigue properties of sulphidized coatings are studied. 45 steel was sulphidized after quenched and tempered, and then tested for their contact fatigue resistance on JP-52 tester. The result shows that the service life of sulphidized samples increased about 1 time compared with that of unsulphidized samples. The effects of elements to contact fatigue properties were analyzed such as contact stress, lubricant, surface defect and roughness, etc.

Key words: Contact fatigue properties, Fatigue life, Sulphidized coatings
