FIELD: process engineering. ^ SUBSTANCE: invention relates to powder metallurgy, particularly to method of producing powder coats on inner surfaces of cylindrical parts. Proposed method comprises applying coat from self-fluxing powder in flame spraying process on steel insert, fitting said coated insert into part and drilling it through. Note here that coat is flashed off at 970-1040C and polished, while fitting is made in the part heated to 300C. ^ EFFECT: simplified process, higher quality of coat. ^ 2 dwg, 1 ex |
