Abstract

The paper examines the influence of the increased content of silicon and carbon on the tribotechnical characteristics, structure and phase composition of a new Co–Cr–W–C system wear-resistant alloy. It was found that a joint increase in the content of silicon and carbon (despite the increase in the friction coefficient) leads to a significant decrease in the values of the wear intensity and linear wear. This is associated with the formation of a dense homogeneous oxide film. It is shown that joint doping with silicon and carbon to the upper doping limit provides a slight decrease in weight gain at temperature of 1100 °C.
