FIELD: metallurgy.
SUBSTANCE: invention relates to production of wear-resistant coatings on titanium plate by means of energy of explosive substances and laser radiation and can be used, in particular, in production of materials for friction pairs, braking devices. Three-layer stack of alternating plating layers of copper-nickel alloy and titanium with symmetrical arrangement of titanium plate relative to clad layers and specified ratio of thickness of layers is made. Packet is welded by explosion, after that hot rolling is performed with reduction down to the specified thickness. Thermal action on the rolled workpiece is carried out with a scanning laser beam in series on the side of each layer of copper-nickel alloy with melting of metal layers. Speed of beam movement relative to processed surface and its diameter is selected from condition of obtaining of titanium layer penetration to specified depth with formation wherein on surfaces of titanium plate of high-strength wear-resistant coatings consisting of titanium and components of copper-nickel alloy.
EFFECT: invention enables to obtain high-strength wear-resistant coatings without pores, cracks and other defects with low susceptibility to brittle fracture under dynamic loads.
