Investigates the antiwear and antifriction properties of friction modifiers under moderate frictional conditions in a PF-1 tester and a ChShM (4-ball) tester, so as to obtain an idea of whether these compounds could be used in motor oils. Compares certain amidothiophosphates (obtained by the interaction of dialkyl- and bis(alkylaryl)thiophosphoryl chlorides with diethylenetriamine) with zinc dialkyl and bis(alkylaryl)dithiophosphates. Considers amidothiophosphates as possible sulfur donors as a basis for studying their capability for improving the antifriction properties of ash-containing friction modifiers, particularly oil-soluble molybdenum compounds. Concludes that amidothiophosphates can be regarded as effective ashless antifriction and antiwear additives for motor oils; that they play the role of a sulfur donor; and that the use of these additives gives a considerable increase in the antifriction efficiency of ash-containing friction modifiers, in particular oil-soluble molybdenum compounds.
