Title: Abrasive wear resistance of electrospark coatings on titanium alloys
Keywords: Wear resistance Electrospark deposition Titanium alloys Coat

Abstract: According to most researchers, improving the tribological characteristics of titanium alloys at this stage is most appropriate through surface modification tribotechnologies. In the present work, the qualitative characteristics of coatings of tungsten-free hard alloy materials materials based on TiC, TiN TiCN TiB2, applied on the most popular titanium alloy Ti6Al4V by electrospark deposition with low pulse energy are investigated. The influence of the electrode materials, the process parameters, the characteristics of the coatings and the roughness parameters on their wear and abrasion resistance has been studied. It was found that the use of coatings from the studied electrodes shows an increase in abrasion resistance by 1.5 - up to 3 times compared to that of the substrate and the electrode materials and process parameters were determined, in which maximum wear resistance was obtained.
