项目摘要
Using R134 as a refrigerant and polyalkylene glycol, and polyolester, polyvinylether, the fiction and wear characteristics of Al-Si alloys, which appear to be promising due to their low density and high strength-to-weight ratio, sliding against steels in R134a with different additives. The results obtained are as follows.1. The solubility characteristics of R134a in oilsIt was confirmed that the dissolution of R134a into oils brought about the reduction of their viscosity leading to the decrease in oil film thickness or to the oil film rupture.The degree of reduction in viscosity was affected not only by the concentration of R134a in oils but also by the mean molecular weight of oils.2. The effect of R134a dissolution on oil film formationOil film thickness was measured by means of an optical interferometry technique with a ball/plate reciprocating apparatus. As the solubility of R134a in oils increased, the oil film thickness became thinner and the amount of Al-Si alloys increased.3. Wear characteristicsThe friction and wear performance was examined with steel/steel and steel/Al-Si alloys pairs in R134a using a reciprocating sliding contact apparatus. With steel/steel pairs, the friction and wear characteristics were significantly affected by absorbed and/or reacted films formed on the rubbing surfaces, and the solidified films on oils. On the other hand, for steel/Al-Si alloys pairs, the wear characteristics of Al-Si alloys was mainly controlled by the transfer property of alloys to the mating steel surface, which was promoted as the polarity of oils became high leading to an increase in the wear.
使用R134作为制冷剂和聚亚烷基二醇、多元醇酯、聚乙烯醚,铝硅合金由于其低密度和高强度重量比而在具有不同添加剂的R134a中与钢滑动,其摩擦和磨损特性似乎很有前途。得到的结果如下: 1. R134a在油品中的溶解特性经证实,R134a溶解到油品中会导致油品粘度降低,导致油膜厚度减小或油膜破裂。粘度降低程度不仅受油品中R134a浓度的影响,还受油品平均分子量的影响。 2. R134a 溶解对油膜形成的影响油膜厚度通过光学干涉技术用球/板往复装置测量。随着R134a在油中溶解度的增加,油膜厚度变薄,Al-Si合金含量增加。3.磨损特性使用往复滑动接触装置对 R134a 中的钢/钢和钢/铝硅合金对的摩擦和磨损性能进行了检查。对于钢/钢对,摩擦和磨损特性受到摩擦表面上形成的吸收和/或反应膜以及油上的固化膜的显着影响。另一方面,对于钢/铝硅合金对来说,铝硅合金的磨损特性主要受合金向配合钢表面的转移特性控制,随着油的极性变高,导致磨损增加,这种转移特性得到促进。
