Examination of Selective Transfer Phenomenon
The paper describes investigation of possibilities of generation of selective transfer phenomenon in sliding friction couples that consist of copper cooperating with steel in glycerol, which serves as model liquid that promotes this phenomenon. Several types of copper employed for production of electric traction wires were used for samples cooperating with samples made of carbon steel. Tribological tests carried out at stepwise increasing load demonstrated that in this type of couples (copper-steel instead copper alloy-steel) the selective transfer phenomenon can occur with intensity depending on slight differences in content of additives and impurities present in copper.
