coating of the surface of a substrate using the thermal spraying method, character ized in tha t the selection is carried out through independently eval- uating a material factor affecting the resistance to slurry erosion and a mater ia l factor affecting the resistance to cavitation erosion. The method allows the selection of the mater ia l factor affecting the resistance to cavitation erosion. The method allows the selection of the material of the coating film without the evaluation test for individual hard coating films, which leads to the significant saving of the time and cost required for the selection of the material of a coating film.
