Influence of processes of secondary structure formation on tribological behavior of composite coatings for sliding friction units
The paper deals with the processes that occur on surfaces of composite coatings of bronze-PTFE and carbon - glass fiber - epoxy resin compositions during their friction against a steel counterbody. Data on the morphology and roughness of their surfaces as well as on their structure and composition are obtained. The study of the materials was carried out by examining laboratory specimens and a sliding bearing after its operation. The effect of oxidation and secondary structure formation on changes in the friction coefficient is found
