Abstract
The lubricant composition of the invention is very effective in extending the fatigue life and increasing the corrosion resistance of the machine parts lubricated therewith. The lubricant composition comprises two types of essential additives of (a) a dithiocarbamic acid ester and/or an alkyl thiocarbamoyl compound and (b) a 1,3,4-thiadiazole compound admixed with the lubricant base material each in a limited amount. In addition to the above mentioned advantages, the resistance against scoring can further be increased by the admixture of the lubricant composition with a third additive (c) such as sulfurized olefins, sulfurized oils, sulfurized oxymolybdenum dithiocarbamates, sulfurized oxymolybdenum organophosphordithioates, phosphoric acid esters and phosphorous esters.
