采用离子渗镀技术在Ti6Al4V合金表面形成均匀致密的钼氮陶瓷渗镀层,对陶瓷层微动摩擦学性能进行研究。100000周次微动磨损试验结果表明,渗镀的Mo-N陶瓷层显著提高了Ti6Al4V合金的抗微动磨损能力。Ti6Al4V合金微动磨损机制是粘着与磨粒磨损的综合效应,Mo-N陶瓷层微动磨损机制是犁削。
The ion-plating technology was used to form uniform and dense molybdenum-nitrogen ceramic coatings on the surface of Ti6Al4V alloy. The tribological properties of the ceramic coatings were studied. The fretting wear test results at 100000 cycles show that the Mo-N ceramic coating significantly improves the fretting wear resistance of Ti6Al4V alloy. The fretting wear mechanism of Ti6Al4V alloy is the combined effect of adhesion and abrasive wear. The fretting wear mechanism of Mo-N ceramic layer is plowing.
