One of the main functional features of an electrode for resistance welding is its wear resistance, which is determined, chiefly, by the level of material strength properties in the range of temperatures developing on its surface. In the work, we propose a scheme of thermodeformational treatment of dispersion-hardened electrode alloy of Cu–Cr–Zr system, which is based on application of intensive plastic deformation, combined with special heat treatment. It is shown that at treatment of the alloy by the developed scheme, the highest level of strength properties is reached in the rod billets in the temperature range up to 450 °С. It ensures an increase in electrode wear resistance by 15 % at spot welding. 15 Ref., 3 Tabl., 6 Fig. . [ABSTRACT FROM AUTHOR] |
