One of the urgent problems in mechanical engineering is development of efficient inexpensive thick-layered coatings for repair worn-out large-sized parts. To solve these problems a comparatively new method of electro-plating with simultaneous mechanical impact of a tool upon coating under formation is promising enough. In this paper there are considered the peculiarities of plating through this method of thick-layer electro-mechanical iron plating on medium carbon steel 30 and 38 ChN3MA, and the composition, structure and properties of coatings obtained are analyzed. Coatings were applied upon crank main journals made of steel 38ChN3MA and upon models imitating crank main journals made of steel 30. Micro-hardness of the coating obtained, roughness, a chemical composition and a structure were analyzed. The results of the investigations have shown that a more significant role in hardness increase is played not by a chemical composition of medium carbon steel upon which it is applied, but a preparation of the surface and the technology of coating and also an electrolyte composition. The structure of electro-mechanical plating is less defective, contains a value of detrimental impurities considerably lower of allowable values and has a satisfactory adhesion strength with a substrate.
