The work examines the issues of ensuring uniform hardness of coatings sprayed by a HVOF method onto parts complex-profile surfaces with their subsequent grinding. A formula is proposed on the basis of which the relationship between grinding modes and the final coatings hardness is assessed. Experimental studies were carried out to confirm the proposed theoretical relationship. Based on the research results, grinding modes were determined that ensure the coating final hardness greatest uniformity.

摘要

The work examines the issues of ensuring uniform hardness of coatings sprayed by a HVOF method onto parts complex-profile surfaces with their subsequent grinding. A formula is proposed on the basis of which the relationship between grinding modes and the final coatings hardness is assessed. Experimental studies were carried out to confirm the proposed theoretical relationship. Based on the research results, grinding modes were determined that ensure the coating final hardness greatest uniformity.
