Tribochemistry and EP Activity Assessment of Mo‐S Complexes in Lithium‐Base Greases
Advances in Tribology, Volume 2008, Issue 1, 2008., 2008 The blends of bis(1,5‐diaryl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) complexes in lithium‐base grease are evaluated for their extreme pressure activity in a “four‐ball test” using 12.7 mm diameter alloy steel ball specimen. The additive, bis(1,5‐di‐p‐methoxyphenyl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) and bis(1,5‐di‐p‐chloro‐phenyl‐2,4 ...
