A method for coating a surface of a turbine component with an environment-resistant and wear-resistant material includes the step of cold gas-dynamic spraying a powder material on the turbine component surface, the powder material comprising a mixture of MCrAlY powder and an abrasive powder such as cubic boron nitride, diamond, carbides, and oxides, with M being selected from Ni, Co and mixtures thereof. The method can further include the step of heat treating the turbine component after the cold gas-dynamic spraying. Thus, the present invention can be employed to greatly improve the performance and the durability of HPT components, and dramatically prolong their service life.
