查询词典 lubrication

To make further progress in understanding gasoline lubricating behaviors, EHD traction and optical film thickness measurements of gasolines and MTBE in point contacts were carried out and compared with those of diesel fuels and hexadecane. Research is directed to understand how thin the films will be formed by gasoline fuels, and how is the transition from elastohydrodynamic to boundary lubrication.

为了进一步研究汽油的润滑行为，测量了汽油及MTBE的弹流润滑牵引力和油膜厚度，考察作为粘度最低的液体燃料的汽油生成的弹流膜究竟有多薄，以及如何由弹流润滑向边界润滑转变。

Interposing a fluid film that completely separates the sliding surfaces results in fluid—film lubrication .

流体膜可能是故意引入的，例如汽车主轴承中的机油，也有可能是无心引入的，例如光滑的橡胶轮胎与湿路面之间的水。

The lack of oil lubrication bad: or partially inflated are lubricative bad characteristics.

润滑不良：缺油或部分油温过矮都是润滑不良的特征。

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.

结果表明，复合材料涂层与基体形成良好的冶金结合，微观组织细小、均匀；复合材料涂层硬度达400HV，约为基体的2.5倍；在室温油润滑条件下，滑动磨损试验表明复合材料涂层摩擦系数和失重均小于基体，磨损表面划痕较浅且平滑，无明显的犁沟、粘着、剥落现象；激光表面合金化显著提高了材料的耐磨性。
