An anti-fretting coating composition that is operationally stable at temperatures of 800° F. to 2650° F. is provided. The anti-fretting coating composition primarily includes cobalt and aluminum oxide and may also include other modifying phases that enhance the overall tribological performance. A component coated with the anti-fretting coating composition is also provided. The component includes a substrate having a first contact surface shaped to cooperate with a second contact surface of an abutting member in a manner which can develop wear between the first contact surface and the second contact surface. The first contact surface includes an anti-fretting coating thereon formed from the disclosed anti-fretting coating composition.

Anti-fretting coating composition and coated components

A composition, a machine component coated with the same, and a method of coating the machine component are provided. The composition includes a CoNiCrAlY alloy, where three or more elements of the CoNiCrAlY alloy are present in equimolar amounts, one of the three or more elements of the CoNiCrAlY alloy being aluminum (Al), and where a molar fraction of Al is between about 0.20 and about 0.25. The composition further includes a transition metal boride including at least one of: cobalt boride (CoB), titanium boride (TiB), zirconium boride (ZrB), tantalum boride (TaB), niobium boride (NiB), or molybdenum boride (MoB), and a refractory alloy.

Boride-reinforced aluminum-containing high entropy alloy composition

A method includes applying a material coating on a surface of a machine component using a thermal spray, wherein the material coating is formed from a combination of a hardfacing material and aluminum-containing particles. The method also includes thermally treating the material coating to generate an oxide layer comprising aluminum from the aluminum-containing particles, wherein the oxide layer is configured to reduce oxidation of the hardfacing material.
