| 摘 要： | 研究了一种以羟基硅酸铝为主的陶瓷润滑油添加剂对钢-钢接触疲劳及磨损性能的影响。利用球-棒疲劳试验机进行试验，证明该陶瓷添加剂提高了摩擦副接触疲劳寿命L10 1．3倍，改善了钢的磨损性能。通过扫描电镜分析，发现在点蚀坑内和点蚀坑的边缘存在微裂纹被覆盖的现象；纳米压痕测试结果表明，接触表面已经形成了一层白亮色物质，并具有极高的硬度。它们可以解释陶瓷添加剂提高接触疲劳寿命及改善磨损性能的原因。 |

| Abstract: | The effect of a ceramic additive with the main composition of Al_4Si_4O_ 10 (OH)_8 in lubricating oil on the contact fatigue and wear performance of steel/steel friction pair was investigated on a ball-rod contact fatigue tester. The anti-fatigue mechanism of this additive was analyzed by means of scanning electron microscopy (SEM) and nano-indenter test. The results show that the ceramic additive can raise the contact fatigue life L_ 10 to 1.3 times, and improves the friction performance of the steel significantly. The micro-cracks in pits and their edages formed during friction and wearing are covered by a bright substance with a quite high hardness of 14GPa.The anti-fatigue mechanism of the ceramic additive is mainly due to the new substance formed on the worn surface, which is beneficial to increase the contact fatigue life and improve the friction performance of the steel. |
| Keywords: | ceramic additive contact fatigue wear SEM nano-indenter test |
