Abstract
A new method for obtaining high-entropy alloys in the near-surface layer of a metal substrate is proposed. As a metal base, steel containing impurities of chromium, nickel and titanium is used. An ion-plasma method is applied to this substrate with an AlFe043 alloy 15 microns thick. Then the resulting coating was irradiated with a laser. As a source of laser radiation, a neodymium-doped aluminum-garnet laser was used. The duration of the flash of the laser pumping lamps operating in the free-running mode was 2×10-3 s. The energy of the laser pulse was 1 J, the repetition rate of the laser pulses was controlled from 0.1 to 35 Hz. Elemental analysis showed the formation of high-entropic coating with high performance characteristics.
