FIELD: powder metallurgy. SUBSTANCE: method involves providing plasma spraying of powder of equiaxial granular microstructure onto heated article surface to be recovered; performing hot compaction of sprayed layer after heating surface layer of roll and working surface of article to be recovered at contact zone to temperature providing superplastic state of metal powder, with applied compaction force being selected so as to provide deformation of sprayed metal powder along boundary line of equiaxial metal crystalline grains. Apparatus has plasma burner with feeding hopper for spraying powder onto working surface of article, article rotating mechanism, platform, hot roll, working traverse, plasma burners for preliminary heating of article surface to be recovered and of hot roll working surface, screen, hanger, quenching cooling nozzle, and active control sensors. Hot roll is connected through hanger to working traverse. Plasma burners are united into block positioned upstream of hot roll contacting zone in direction of rotation thereof on screen fixed to hanger. Quenching cooling nozzles and active control sensors are attached to screen at site downstream of roll contacting zone in direction of rotation thereof. Article rotation mechanism is mounted on platform. Hot roll working surface has profile similar to that of mirror reflection of article surface to be recovered. Method and apparatus may be used for forming protective coat in repair and recovery of parts. EFFECT: increased strength characteristics of sprayed layer, improved adhesion of sprayed layer with basic metal and reduced power consumption. 9 cl, 5 dwg, 2 tbl
