FIELD: chemistry.
SUBSTANCE: processed surface is prepared by cleaning, washing and abrasive flow machining. That is followed by laser clad deposit of a powder material in an inert gas medium. The powder material is presented by titanium and silicon carbide particles 20-100 mcm in size in mass ratio 6:4 or 6:5. The deposit process is performed at laser power 4÷5 kWt, laser beam travel speed 500÷700 mm/min and power consumption 9.6÷11.9 g/min.
EFFECT: invention enables the defect-free wear-resistance coating with high adhesion to the substrate and minimum effect thereon.
