Environmentally Friendly Technology for Applying Coatings with Various Functional Purposes

The paper presents an environmentally safe technology of combined surface treatment of mechanical engineering parts. It is a method of cladding with mechanical impact by means of a flexible tool. An integrated approach to the appointment of rational treatment modes was considered. On the one hand, the quality characteristics of the formed coating are taken into account, and on the other hand - the durability of the wire tool. The scheme of impact on the treated surface is presented. The main analytical dependences for determining the degree of coverage and the degree of uniformity of the depth of the hardened layer are given. An analytical relationship is presented for determining the maximum actual stresses formed in the pile of a flexible tool as it slides along the contact area of the treated surface. The dependence is based on the theory of flexible elastic rods. Analytical dependencies are given to determine the surface temperature of the workpiece and the relative strength of adhesion of the coating to the substrate. The algorithm for selecting treatment modes for cladding with a flexible tool is presented. The purpose of the algorithm is to promote the formation of coatings with parameters that best match the functional purpose of the treated surface.
