Abstract
Machining of deep holes with a special configuration in parts subjected to intensive wear is realized mainly by electrochemical methods.
The operational, technological and economic parameters of the parts are increased after wear-resistant coatings are deposition them. Electrochemical coatings on parts of aluminum alloys are formed by anodizing, and on steel parts by chrome plating. The presence of coating leads to an increase in the technical resource, reliability parameters - faultlessness, durability, repairability and keeping, corrosion resistance, as well as the main indicators hardness, wear resistance, heat resistance and thermal conductivity. Anodized and chromed coatings are characterized by low levels of residual stresses, high adhesion to the base material and a low coefficient of friction.
The relevance of the issues discussed in the article is determined by the need to create new or more efficient technologies for manufacturing of details with higher durability and wear resistance, operating in conditions of extreme, intensive, cyclic thermodynamic loading. The competitive environment, combined with the exceptional dynamics of the market for products, which include parts with a similar configuration and purpose worldwide, require the improvement of mechanical, thermal, dynamic and tribological indicators to be realized in conditions of constantly increasing productivity and decreasing technological cost while complying with the requirements for preservation, and in a number of cases for improving the geometrical and physico-mechanical qualities of the treated surfaces.
