Abstract
Abstract. The article presents a method for producing a nanostructured wear-resistant high-hard coating with high physicomechanical and strength characteristics, resistance to shock and vibration loads. The result is an increase in adhesion between the substrate and the coating, as well as an increase in microhardness. One of the common methods of metal cutting is band-cutting machines that use closed band saws as cutting tools. Since materials with high physicomechanical characteristics (hardness, strength, etc.) are increasingly being used in modern production, which significantly complicates the cutting process and makes increased demands on the cutting tool. To expand the range of processed materials for which the productive use of band-cutting machines is possible, it became necessary to create a band saw with higher cutting characteristics. At the same time, the specificity of the working conditions of the band saw shows that the blade should have such characteristics as increased vibration resistance, resistance to alternating and dynamic loads, and the cutting part of the saw should have increased resistance to shock, dynamic, alternating loads, have high hardness, as well as increased wear resistance.

The layered composite material proved to be workable under difficult loading conditions on other engineering products and firmly strengthened its position in the production, since with the correct analysis of the working conditions of the product, whether it be a part or a cutting tool, in particular a band saw blade, it can be found that this or that zone or layer can work on a specific type of loading
Using magnetron-plasma spraying, nanostructured metal thin-layer films of the desired chemical composition and thickness are applied with high adhesion, which is close in value to metallurgical
Summary
One of the common methods of metal cutting is band-cutting machines that use closed band saws as cutting tools. The layered composite material proved to be workable under difficult loading conditions on other engineering products and firmly strengthened its position in the production, since with the correct analysis of the working conditions of the product, whether it be a part or a cutting tool, in particular a band saw blade, it can be found that this or that zone or layer can work on a specific type of loading. It can be made of a material with characteristics that satisfy these load conditions.
