采用球-板式摩擦磨损试验机，研究了合金钢成分对二硫代氨基甲酸钼MoDTC摩擦磨损特性的影响。使用的油是一种纯碳氢化合物的角鲨烷。采用Mo质量%为4.25、Cr质量%为4.12的高速钢M50和Cr质量%为0.45的轴承钢SUJ2获得了优异的摩擦磨损性能。特别是采用Mo和Cr含量高的M50作为上球试样，摩擦系数很低。预先形成的MoO3表面膜可有效改善MoDTC的摩擦磨损特性。
The effects of composition of alloy steel on the friction and wear characteristics of molybdenum dithiocarbamate MoDTC were studied in reciprocated sliding contact using a ball-on-plate type tester. The oil used was squalane of a pure hydrocarbon. The excellent friction and wear characteristics were obtained with high speed steel M50 containing Mo at 4.25 and Cr at 4.12 mass % and bearing steel SUJ2 containing Cr at 0.45 mass %. Especially, M50 with high Mo and Cr content used as the upper ball specimen gave a very low coefficient of friction. A MoO3 surface film formed in advance was confirmed to be effective in improving the friction and wear characteristics of MoDTC.
