Abstract
A method of manufacture is provided which includes steps of: providing a component body of an engine component for a turbine engine; and applying a coating onto the component body using a cold spray process. The applying of the coating includes impinging coating feedstock material against the component body to form the coating. The feedstock material includes a mixture of metal powder and grit particles. The grit particles include solid metal oxide particles and/or solid carbide particles.

A method of manufacture, comprising:
- providing a component body of an engine component for a turbine engine;
- and
- applying a coating onto the component body using a cold spray process, the applying of the coating comprising impinging coating feedstock material against the component body to form the coating, the feedstock material comprising a mixture of metal powder and grit particles, and the grit particles comprising at least one of solid metal oxide particles or solid carbide particles.
A method of manufacture, comprising:
- providing a component body of an engine component for a turbine engine;
- and
- applying a coating onto the component body using a cold spray process, the applying of the coating comprising impinging coating feedstock material against the component body to form the coating;
- the feedstock material comprising a mixture of metal powder and grit particles, the metal powder having a powder particle size between eighteen micrometers and fifty-six micrometers, the grit particles comprising at least one of metal oxide particles or carbide particles, and the grit particles having a grit particle size between seventy-four micrometers and one hundred and twenty-five micrometers.
A method of manufacture, comprising:
- providing a component body of an engine component for a turbine engine;
- and
- applying a coating onto the component body using a cold spray process, the applying of the coating comprising impinging coating feedstock material against the component body to form the coating, and the feedstock material comprising a mixture of metal powder and grit particles, the grit particles comprising at least one of metal oxide particles or carbide particles, wherein a weight ratio of the grit particles is higher than a weight ratio of the metal powder in the mixture.
