This paper discusses the use of electro contact baking of steel powder on a bronze bushing. Its main design parameters are: taper angle of the matrix part - α, deg.; internal diameter of the matrix - D, mm; length of the cylindrical deforming belt - L, mm. To prevent melting of the surface of the restored bronze part, a special electrode was used, which made it possible to bake metal powders onto the bronze surface without melting the part to be restored. The diameter of the crimp die is defined as the difference between the outer diameter of the sleeve before compression and the sum of the wear on the inner surface of the bronze sleeve and the allowance for machining to obtain the nominal size of the inner diameter of the sleeve.
