摘要

对矿物油中分散的二硫化钼(MoS2)粉末润滑的两种实际机构，轴承和链条的磨损进行了评估。在两个测试中观察到磨损之间的密切相关性，并且在轻载荷下，所有二硫化钼样品的测试结果比单独使用清洁油的磨损更大。在实际测试中，二硫化钼粉末的耐磨性与其二氧化硅(SiO2)含量之间没有任何普遍的相关性，而所观察到的严重形式的轴承损坏，再次表明需要一种直接控制这些材料的耐磨性的方法。由于实际测试的时间太长，因此为此目的开发了一种加速测试。

Abrassion by impurities in MoS2 Part 2 — practical tests and the development of a quality control

Wear of two types of practical mechanisms, bearings and chains, lubricated by dispersions of molybdenum disulphide (MoS₂) powders in mineral oil has been assessed. A close correlation between wear in the two tests is observed and at light loads all samples of MoS₂ examined results in greater abrasion than clean oil alone. The absence of any general correlation between the abrasiveness of MoS₂ powders in practical tests and their silica (SiO₂) contents, and the severe forms of bearing damage which are observed, reaffirm the need for a method of direct control over the abrasiveness of these materials. Because the practical tests are far too lengthly for this purpose, an accelerated test has been developed to that end.
