Abstract
The invention relates to an anti-friction coating (11, 12, 41, 42, 43) and an anti-friction coating composite (10) comprising at least 25 vol. % of a binder (16) and comprising fillers, which include zinc sulfide (18) and barium sulfate (20) and optionally additional fillers, wherein the volume ratio of barium sulfate (20) to zinc sulfide (18) is between 0.1 and 15.7, preferably between 0.8 and 4.88, and particularly preferably between 1.5 and 3.44. The anti-friction coating composite (10,40) comprises at least two anti-friction coatings (11, 13) of different compositions. The invention further relates to sliding bearing layered composite materials comprising such coatings and use thereof in internal combustion engines.
