INFLUENCE OF ELECTROSPARK ALLOYING REGIMES AND ELECTRODE MATERIALS ON STRUCTURE AND ABRASION RESISTANCE OF COATINGS

摘要

An analysis of the structure of surface layers of steel 45 and steel R18 hardened by means of electrospark alloying with the electrode substances Ti, Ni, Cu, W, VK6, and T15K6 is conducted. On the basis of X-ray spectra and electron spectroscopy it is concluded that the energy of the process exerts an influence on the parameters of the fine crystalline structure the abrasion resistance of the surface.
