Abstract

The invention relates to the application of metallic coatings of copper alloys on the surfaces of parts and working surfaces of the instrument. The purpose of the invention is to increase the processing performance and quality of the coating by increasing the uniformity and continuity, which is achieved by making the pile from the wire in the solid and semi-solid state, with the amount of semi-solid wire 2 ... 3 times the amount of solid wire, and their distribution pile uniform. 2 Il.

Description

The invention relates to the application of metallic coatings and can be used for the deposition of coatings from copper alloys on the friction surfaces of wear parts made of steel and cast iron, as well as on the working surfaces of the cutting tool.

The purpose of the invention is to increase productivity by eliminating the pre-cleaning operation of the treated surface and improving the quality of the coating by increasing its uniformity in thickness and continuity.

FIG. 1 shows the device section; in fig. 2 is a view A of FIG. one.

The device (brush) consists of two semi-bodies 1, interconnected by bolts 2. In an annular recess of semi-bodies located on the periphery, there are loops and brass wire 3 clamped in a semi-solid and solid state, and the brass wire loops alternate solid wire loop comes 2

or 3 loops of semi-solid wire. In order to protect the loops from falling out of the semi-bodies, they are dressed on the wiring ring A. The diameter of the brass wire, from which the hinges are 0.1 ... 0.3 mm. Speaker of half-corpus pile length 0 ... 12 mm.

The device works as follows.

The rotating brush is brought into contact with the surface to be treated, to which the surface-active working fluid has been previously applied, and is additionally fed to the side of the surface to be treated 1 ... 3 mm. Sliding solid wire in a pile on the surface being treated effectively cleans the surface of oxides and applies a thin preliminary layer of brass. It does not damage the surface to be treated as it does with a steel brush. Following solid brass wire
