Purpose: the technology is designed to produce protective wear-resistant coatings for friction units experiencing combined loads. The proposed technology makes it possible to create a range of different types of composite coatings on iron-containing alloys for different friction speeds and degrees of load by varying the frequency of the reinforcing mesh and the grade of filler powders.
Advantages: the developed type of composite composite materials can be used to replace traditionally used antifriction materials for friction units with the requirements of increased reliability in conditions of sufficiently high specific loads and work in aggressive and severe operating conditions.
Main characteristics: the coating thickness is about 0.5-1.5 mm, the contact zone with the bronze matrix is practically devoid of porosity and is characterized by high continuity.
Economic viability: the cost of a composite part is 0.8...1.3 of the cost of standard products. At the same time, the increase in the durability of hardened parts can be from 3 to 20 times (for example, when using autoclaves and retractable hearths of mini CHP in trolleys).
