Development of physic-technological bases of forming and effective application on nanocomposite gradient coverage of the tribotechnical setting

Description

New fundamental information about the mechanisms of consolidating by modification and heat treatment by the concentrated energy sources of nancomposite gradient coverages is found. On this bases conceptual approach in relation to forming of coverages of tribotechnical and instrumental setting is developed, namely: the method of making of nancomposite gradient coverages is grounded in theory and experimentally; methodological bases of increase of longevity of trybo connections strengthening by nancomposite gradient coverages; criterions ability to work of nancomposite coverages for the superficial consolidating of details of knots of friction; the process of forming of nancomposite gradient coverages taking into account the developed criterions is optimized.

Innovative Aspect and Main Advantages

Technology allows to get coverage with complex inclusion (by macro- and nanoparticles) and high tribotechnical (high wearproof, low coefficient of friction) and mechanical properties (hardness, module of resiliency) due to conducting of chemicothermal treatment

Areas of Application

The developed scientific approach and methods can be applied for strengthening and renewal of details of machines and mechanisms for metallurgy, engineering industry, chemical and light industry, and instrument-making industry and aircraft building
