Keywords: titanium alloys, coatings, electrospark, wear resistance, ha
Abstract: This paper discusses the essence and technological characteristics of the process of electrical spark deposition process (ESD), its advantages and disadvantages with a view to its application for improving the tribological properties of titanium and its alloys. A summary of the available data and results in the literature devoted on the ESD of titanium and its alloys has been made. Based on the data in the literature, a comparative analysis of the technical parameters and technological capabilities of the most common equipment, including contactless ESD, is presented. The geometrical and physico-mechanical haracteristics of the coatings obtained with the different equipment and the nature of their change depending on the technological parameters and the type of anode and cathode materials are shown. Comparative studies of characteristics and tribological properties of ESD hard alloys coatings deposited on titanium alloy Ti6Al4V vere performed.
