合成航空润滑油轴承腐蚀模拟评定方法研究

摘要

在参考国外试验方法的基础上研究建立合成航空润滑油轴承腐蚀模拟评定方法,并规定两种试验标准油,运用该方法对标准油和国内外7种不同类型的合成航空润滑油的轴承腐蚀性能进行模拟评定.结果表明,所建立的方法具有良好的重复性、区分性,规定的两种标准油能够简单可靠地确定试验的有效性.通过本试验方法,可以可靠地对合成航空润滑油的防腐性能进行区分和评定.%Based on the experimental methods abroad, a simulating evaluation method for bearing corrosion property of synthetic aircraft lubricants was established with two kinds of synthetic aircraft lubricants as standard. The bearing corrosion properties of the two standard lubricants and seven kinds of synthetic aircraft lubricant samples at home and abroad were evaluated. The results show that the method has favorable repeatability and distinguishability and those two kinds of standard lubricants can simply and unfailingly ensure the efficiency of the experiment. Through the evaluating method, the bearing corrosion properties of synthetic aircraft lubricants can be distinguished.
