ANALYSIS OF THE MAIN FUNCTIONAL PARAMETERS OF POLYMER SURFACE MICRORELIEF ROUGHNESS

Abstract

The results of the functional parameters of the surface roughness profile after a series of experiments for a single material at different sliding speeds have been analyzed. The study of surface characteristics of materials is of great importance for understanding their behavior and properties under various operating conditions. It is especially important to analyze the roughness parameters after experiments in different modes, as this allows for an understanding of how the surface condition and its interaction with other elements change under different load conditions. Using an optical profilometer for this study provides detailed information about the microstructure of the surface and allows for an objective assessment of changes in its parameters after changes in modes. Given the widespread application of polymeric materials in various industries and engineering fields, it is crucial to investigate their properties and changes during operation. One of the key aspects is studying the wear resistance of polymers under different conditions, particularly at various sliding speeds. In this context, research has been conducted on the impact of sliding speed on the microrelief and wear resistance of polymer materials. Adsorption on surfaces with greater roughness occurs more easily. Thus, a rough surface (counterbody) can adsorb a polymer, whereas a smooth surface of the same material does not. Consequently, roughness can significantly alter the effective interaction between the polymer and the surface.

Tribological pairs between polymers and 30KhGSA steel combine the high mechanical properties and wear resistance of steel with the low friction coefficient and self-lubricating properties of polymers, making them effective for use under significant mechanical loads. Polymers also provide corrosion resistance, reducing the need for additional lubrication and ensuring a longer service life. This combination of materials is widely used in the automotive, aerospace, medical, and other industries where high reliability and cost-effectiveness are essential.
