Influence of Porosity on Mechanical and Tribotechnical Characteristics of Copper-Graphite Composition Materials

EasyChair Preprint 5230

Abstract

The article considers the effect of porosity on the mechanical and tribotechnical properties of copper-graphite and copper + copper-graphite powder composite materials applied in friction joints. It has been found that Cu-C and Cu + (Cu-C) materials obtained after sintering at 18% porosity get the optimal value of hardness and impact viscosity. The highest value of tribotechnical properties has been determined in Cu + (Cu-C) material.
