研究了用PVD法制备TiCN涂层减轻叶片轴承扭转微动磨损的可行性。结果表明，磨屑作为固体润滑剂对摩擦力矩有很大影响。TiCN涂层在油和人工海水中的磨损体积分别减少了97.6%和62.3%，这主要是由于表面硬度的增加。在油中，所产生的硫酸盐和磷酸盐防止摩擦副之间的癫痫发作，并且磨损表面的特征在于抛光磨损。在人工海水中，磨损机制是机械磨损和腐蚀磨损的复合。这项研究表明，TiCN涂层适用于减轻叶片轴承中的微动磨损。
The feasibility of alleviating torsional fretting wear of the blade bearing by preparing PVD TiCN coating was studied. The results show that the friction torque was highly influenced by the wear debris acting as the solid lubricant. The TiCN coating reduced the wear volume by 97.6% and 62.3% in oil and artificial seawater, respectively, which was mainly due to an increase in surface hardness. In oil, the produced sulfates and phosphates prevent seizures between the friction pair and the worn surface was characterized by polishing wear. In artificial seawater, the wear mechanism was a combination of mechanical wear and corrosion wear. This study reveals that the TiCN coating is suitable for alleviation of fretting wear in the blade bearing.
