Effect of Copper Content on Tribological Characteristics of Fe−C−Cu Composites

详细

The paper presents the results of an investigation of the effect of the copper content on the tribological characteristics of Fe−C−Cu composites. It has been shown that the best tribological properties and hardness are shown by material containing 3% copper. In the case of a 10% copper concentration, the wear rate of the composite rises by as much as ten times, while at a 20% concentration, it decreases. It has been proved that the copper concentration significantly affects the formation of friction surface morphology.
