Abstract
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.
Claims20
A method, comprising:
- applying a material coating to 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;
- and
- 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.
A method, comprising:
- forming a mixture of a hardfacing material and aluminum-containing particles;
- applying the mixture onto a substrate using a thermal spray to form a material coating;
- and
- pre-heat treating the material coating to generate a scale layer formed from the aluminum-containing particles, wherein the scale layer is configured to improve a wear resistance of the material coating.
A method, comprising:
- applying a material coating to a surface of a machine component using a thermal spray, wherein the material coating comprises a first plurality of phases of a hardfacing material and a second plurality of phases of an aluminum-containing material, and wherein the aluminum-containing material is configured to oxidize to reduce beta depletion of the hardfacing material.
