TITANIUM AND TITANIUM ALLOY WITH LUBRICANT COATED SURFACE

摘要

Minimizing the galling of titanium (or alloys) in sea water by first providing a conversion coating such as an impregnated coating of polytetrafluoroethylene, then overlaying with a coating of molybdenum disulfide and a final outer coating of asphaltic grease. An apparatus for evaluating galling of titanium wires under extreme pressure wherein a rope or wire is supported on a reciprocating weighted crank arm and abuts a stationary wire. The weighted arm applies the necessary pressure and imparts relative motion between the wires, and thereby causes repeatable galling results.
