Equpment, materials and technology of plasma hardfacing of press-moldsusing axial feeding of flux-cored wire.Aim is increasing efficiency of plasma hardfacing, the development of new compositing of flux-cored wires. The theoretical and experimental methods of investigationa used.The heating electrode wire, which is fed along the plasma arc axis the heat flows into the wire sheath is studied. The possible reactions of components is estimated. Results have been implement in hardfacing of a number of parts and tools operating in aggressive medium and at alternating thermal cycles. The efficiency have been increased 4 times.
