Abstract

The article presents the results of studies of adhesive, strength and tribotechnical properties of composite polycaproamide polymer materials and coatings based on them for mechanical engineering purposes. It has been established that the relative change in the adhesion strength depends on the degree of filling in air and in argon has an extreme character passing through a maximum for coatings based on PCA with aluminum oxide, and for coatings made of PCA with copper oxide, it has a complex character. The formation of adhesive, strength, and tribotechnical properties of filled polycaproamide coatings was also studied. At the same time, it was found that by adjusting the temperature-time technological modes, it is possible to increase the adhesive, strength, and tribotechnical characteristics of composite polycaproamide coatings for machine-building purposes.

Highlights

Today, on a global scale, much attention is paid to improving the efficiency, performance, and durability of machines and mechanisms
Of particular importance is an increase in the adhesive and strength properties of coatings made of composite polymer materials and a decrease in their coefficient of friction and wear, which ensure an increase in the service life of the working bodies of machines and mechanisms [1,2,3,4,5,6,7,8,9,10,11,12,13,14]
This work aims to study the mechanism of contact interaction of materials, adhesive, strength, and tribotechnical properties of composite polymer materials and coatings based on them for

Summary

Introduction

On a global scale, much attention is paid to improving the efficiency, performance, and durability of machines and mechanisms. A study to identify the relationship between the friction composition with other physical and mechanical properties of the adhesive and the substrate and coatings is an urgent task.
