Method for coating components used in gas turbine engine of aircraft, involves providing coating material in form of powder particles that are prepared by performing mechanical grinding process at low temperature

摘要

The method involves providing coating material in form of powder particles (9) for performing the high-speed cold gas spraying process on to-be coated surface of a component (1). The powder particles are welded with each other. An adherent coating (2) is formed at the material on the component surface. The powder particles are prepared by performing mechanical grinding process at low temperature.
