摘要：

The fracture strength of copper-based binary substitutional solid solutions was studied under dry friction. It is shown that an essential factor influencing the wear resistance of copper alloys is a local internal distortion of the crystal lattice due to the difference between the atomic radii of the basis metal and the alloying element. It is found that the wear resistance of a substitutional solid solution can be increased by substituting an alloying element with a larger atomic radius for copper atoms and can be decreased in the opposite case. A model is proposed relating the experimental dependences of the wear characteristics of alloys to a change in the interatomic bonding strength caused by doping of the matrix with atoms of various radii.
