Combined materials having a high-strength and wear-resistant work surface are used in the material processing industry. To obtain materials, which can provide high wear resistance indicators, complex technological equipment is required. It is also possible to use materials having a hard base with a protective coating of wear-resistant high-hardness material. Therefore, a method of resistance welding for applying a coating of commercially pure titanium to the surface of highspeed 1.3343 tool steel (analogue of R6M5) and subsequent modification of the titanium surface and the entire assembly by high-temperature induction heating to obtain a wear-resistant oxide coating is considered in this work.
The results of a study of the dependences of the inductor current and heating kinetics on the power consumption value for titanium samples in the course of treatment with high frequency currents in the range from 88 to 120 kHz were presented. The effect of the inductor current in the range from 0.6 to 8.5 kA on the heating kinetics of equimass samples of disk and cylindrical shapes in the temperature range from 800 °C to 1700 °C in air was established. It was shown that the kinetics of a one- and two-cycle induction treatment had differences at the alpha-phase temperature.
