ABSTRACT:
Coated gas turbine engine hardware is described. The hardware comprises a titanium alloy substrate having a coating thereon consisting essentially of titanium nitride wherein the ratio of nitrogen to titanium is greater than one. Such coatings have a residual compressive stress state which aids in minimizing the fatigue debit which would otherwise result from the use of a hard coating on a titanium substrate. Coatings are applied by the use of a vacuum arc deposition process.
