Tribotechnical characteristics of titanium diboride electrospark coatings

Conclusions The tribotechnical characteristics of an alloyed layer obtained by electroerosion hardening of 45 steel with TiB₂-Mo sintered materials were studied. It was established that at increased temperature the maximum wear resistance is possessed by a hardened layer in alloying with a material containing the optimum quantity of hard and plastic phases. A higher content of hard phase leads to brittle failure of the hardened layer and an increased content of plastic phase to seizing of the contacting pairs.Translated from Poroshkovaya Metallurgiya, No. 5(269), pp. 86–88, May, 1985.
