Abstract
A pair of mating titanium alloy substrates for use in a gas turbine engine are provided, one of which comprises an aluminum bronze alloy wear resistant coating. The coating consists essentially of 9.0-11.0% aluminum (Al), 0.0-1.50% iron (Fe), and a remainder of copper (Cu). The wear resistant coating is disposed between the mating substrates and inhibits frictional wear between the mating substrates.

A pair of mating titanium alloy substrates for use in a gas turbine engine, comprising:
- one of said mating titanium alloy substrates having an aluminum bronze alloy wear resistant coating, said coating consisting essentially of 9.0-11.0% Al, 0.0-1.50% Fe, and a remainder of Cu;
- wherein said wear resistant coating is disposed between said mating substrates and inhibits frictional wear between said mating substrates.
A method for minimizing frictional wear between a pair of mating titanium alloy substrates, comprising the steps of:
- providing an aluminum bronze alloy powder consisting essentially of 9.0-11.0% Al, 0.0-1.50% Fe, and a remainder of Cu;
- and
- applying said aluminum bronze alloy powder to one of said titanium alloy substrates, thereby forming a coating on said one substrate.
