Mechanism of formation of antifriction coating with geomodifiers
Considered are a number of antifriction compositions for no-dismantle repair of worn-out contact surfaces of various machines, including reciprocating engines, based on fine-grained powder from mineral serpentines or friction geomodifiers (FGD). Structure and properties of coatings on rebuilt parts were studied, whereupon a hypothesis of FGD-based coatings formation on engine parts exposed to lube oil was offered. Said hypothesis accounts for coating build-up even after FGD is removed from lube oil.
