Abstract
In the study, morphology, composition, and hardness of the coatings formed by electrospark alloying (ESA) of titanium with zirconium and subsequent induction heat treatment were considered. The possibility of forming coatings with a maximum size of oxide crystals of 8.9±3.8 μm and an open porosity reaching 58 % was established. The morphology parameters depend on the modes of electrospark alloying and heat treatment. There was a decrease in zirconium content in the coating composition from 21.9 to 1.1 at.% when the temperature and duration of induction treatment were increased. Maximum hardness equalled 10.3±0.3 GPa.
