The process of hardening of the mining equipment by detonation spraying has been considered. The aim of the work is the hardness increase, anti-friction properties and wear resistance of machines parts surfaces, such as bushings, of hydrocylinder joints of boom and the bucket, crowns, etc., which are made from copper-based alloys.
Mining equipment: classification, maintenance. Modern mining equipment enables to automatize the most important and complex processes of carrying out extracting, and other works in mines and open pits. In order to provide regular functioning of high-tech machines, specialists hold quality maintaining of the mechanisms.
