Abstract

The effect of treatment by Fe-anode in the electric-spark alloying (ESA) process of the iron sample surface by transition metals, which were applied according to the Me-Fe-Me scheme, where Me - Cr, Cu, Ni, Ti, W, Zr, on the wear resistance of the resulting coatings was investigated. Testing of samples with coatings under dry friction-sliding conditions «plane by plane» for 10 hours showed an increase in wear resistance to 4.92–12.64 times compared to the original sample that was not alloyed.
