DEVELOPMENT OF THERMAL TREATMENT WITH DOUBLE – PHASE RECRYSTALLIZATION OF THE COMPOSITE OF HIGH – CUTTING STEEL P6M5 WITH CONSTRUCTION STEEL 35ГЛ

The article concerns the technology of thermal of working surfaces of soil – cutting tools manufactured from the composite of high – cutting steelP6M5. With construction steel Achievement of high working properties of the 35ГЛ sail – cutting tools at the lowering of their manufacturing cost is the application of bimetallic compositions with the simultaneous development of new methods of the thermal treatment the off real method allows increasing the parenteral of soil –cutting part in 8–10 times as to devising the devising the manufacturing in 2–3 times
