Іnfluence of tribotesting on microhardness of polymers

Abstract

This study investigates the microhardness of the polymeric material Zedex zx-100k and other polymers following tribological testing at different sliding speeds. The primary objective of this research is to select polymers for potential use in composite materials. Microhardness was determined using a ПМТ-3 microhardness tester by indenting diamond indenters into samples in various zones – on the initial surface of the material and in the wear area. The results obtained allow evaluating the influence of sliding speed on the change in microhardness of the polymeric material and its behavior under wear conditions. Additionally, the results enable comparison of different polymers tested on a tribometric setup with subsequent assessment of their physical characteristics. The research highlights the importance of understanding the tribological properties of polymers, as these materials are increasingly being used in various industrial applications due to their favorable characteristics, such as low weight, cost-effectiveness, and chemical resistance. The selection of suitable polymers for composite materials is crucial for enhancing the performance and durability of products in which these materials are used. Moreover, the study provides insights into the mechanisms of wear and the role of microhardness in the wear resistance of polymers.
