摘要

本文讨论了复合摩擦涂层对滑动副摩擦学参数的影响。采用PVD法在AISI4337钢试样上形成a-C:H涂层。采用10W40生物降解机油润滑AISI 4337钢和SAE-48轴承合金对进行滑动摩擦磨损试验。结果表明，钢表层和a-C:H涂层对摩擦系数和温度有显著差异。在有a-C:H涂层的摩擦副中，摩擦副的测试参数高于有钢表层的摩擦副。a- c:H涂层对SAE-48轴承合金的磨损比钢表面对SAE-48轴承合金的磨损更严重。摩擦副中使用的表面层会导致发动机油的润滑性能恶化，降低其抗磨损性。

TRIBOLOGICAL PROPERTIES OF THE FRICTION PAIR WITH a-C:H COATING UNDER THE CONDITIONS OF LUBRICATION WITH 10W40 BIODEGRADABLE ENGINE OIL

The present study discusses the influence of an a-C:H coating on the tribological parameters of sliding pairs under mixed friction. Using the PVD method, the a-C:H coating was formed on specimens made from AISI 4337 steel. The sliding friction and wear process was carried out on the pairs of AISI 4337 steel and SAE- 48 bearing alloy, which were lubricated with 10W40 biodegradable engine oil. The investigation showed significant differences in the friction coefficient and temperature in the tested pairs with the steel surface layer and the a-C:H coating. In the friction pairs with the a-C:H coating, the tested parameters of friction were higher than in pairs with the steel surface layer. The pairs with the a-C:H coating showed more intensive wear of the SAE-48 bearing alloy than those with a steel surface. The surface layer used in a friction pair leads to the deterioration of the lubricating properties of engine oil and reduces its resistance to scuffing.
