Friction is classified as the main dominant element having an adverse influence on materials' lifespan and performance. Friction between any sliding contacts is continually accompanied by heat generation and shear force. The surface deterioration produces destruction in the component and reduced the life expectancy of the components.

Polymer Composites, 2021
AbstractThe formation of transfer layer especially in polymer‐based composites is unavoidable and essential to investigate the effectiveness of transfer layer under working conditions as it decides the material removal between mating parts. The main aim of the present work is to analyze the performance of transfer layer on specific wear rate (SWR) and ...
