Experimental Study on the Tribological Behavior of Polymeric Materials Used in Sliding Motion Couples

Abstract

The use of polymeric materials with thermoplastic properties, in the different types of rubbing couplings, is of scientific and technical interest. Due to the mechanical and technical properties superior to the metallic materials, a thorough analysis of the behavioral mode in operation is necessary, which justifies the development of research in this field. The objective of this paper is to carry out an experimental study on the tribological behavior of the Relamid polymeric material, on a tribological test stand in contact with a harder surface (OL42). The material under analysis is a thermoplastic, high performance material used to make the organs of moving machines. It is used in the construction of many couplings with sliding motion due to the good wear behavior under the action parameters. The experimental data obtained show that the wear of any car body is affected by the operating conditions (pressure, speed) and the material of the coupling. As a result of the experimental results obtained, it is appreciated that optimal constructive solutions can be found from the point of view of the phenomena related to friction, wear and tear for choosing such material.
