采用四球机考察了二烷基二硫代磷酸钼(MoDDP)、二烷基二硫代氨基甲酸钼(MoDTC)、非硫磷有机钼等3种有机钼化合物以及三氧化钼、钼酸铵2种无机钼化合物在润滑脂中的抗磨性能。结果表明:3种有机钼化合物在润滑脂中都有良好的抗磨性能,特别是高浓度的MoDDP在高负荷下仍具有优良的抗磨性能,非硫磷有机钼在低负荷下的抗磨性能比较突出;2种含钼固体无机化合物在润滑脂中也具有良好的抗磨性能,特别是钼酸铵,这为直接应用于润滑脂中提供了可能。
Three kinds of organic molybdenum compounds such as molybdenum dialkyl dithiophosphate (MoDDP), molybdenum dialkyldithiocarbamate (MoDTC) and non-thiophosphorus organic molybdenum were investigated by the four-ball machine. And three molybdenum trioxide, ammonium molybdate 2 Anti-wear properties of inorganic Molybdenum compounds in greases. The results showed that the three kinds of organic molybdenum compounds have good anti-wear properties in grease, especially the high concentration of MoDDP still has excellent anti-wear performance under high load, non-thiophosphorus organic molybdenum under low load anti-wear Performance is more prominent; two kinds of molybdenum-containing solid inorganic compounds also have good anti-wear properties in greases, especially ammonium molybdate, which is directly applied to the grease may provide.
