PROMISING METHODS OF HARDENING AND RESTORATION OF PARTS OF MODERN MECHANICAL ENGINEERING

Abstract

The article assessed the effectiveness of laser surfacing technology designed to restore metal parts subject to high wear, dynamic loads and mechanical influences during operation. Laser surfacing, as a new technology based on the use of lasers and nanomaterials to harden alloys, is an effective method of restoring worn parts or improving the strength characteristics of new mechanisms and machines. This technology allows the material to be precisely applied to the surface of the parts, which ensures high accuracy and quality of restoration. As a result of the use of laser surfacing, it is possible to significantly increase the service life of 
parts and ensure their reliable operation under conditions of increased operational load. This makes this technology in demand in various industries where high wear resistance and strength of parts and mechanisms are required. Additionally, laser surfacing is characterized by high efficiency and cost-effectiveness of the parts restoration process. Due to the possibility of using a variety of materials and precise control 
of the application of a layer of material to the surface, this technology minimizes waste and reduces production costs. Moreover, laser surfacing is capable of restoring not only surface defects, but also improving the mechanical properties of the material, which increases its strength and durability. Thus, the use of laser surfacing in production promises significant benefits, including increased resource efficiency, reduced maintenance costs and improved quality of the final product.
