COMPLETE SOLID-SOLUTION POWDER FOR CEMENTED CARBIDE, CEMENTED CARBIDE CONTAINING PLATELET CARBIDES, COATED CEMENTED CARBIDES AND PROCESSES FOR PREPARING THEREOF

摘要

PURPOSE: complete solid-solution powder cemented carbide sintered body contains board-like carbide, coated hard alloy and its manufacturing method to manufacture cutting tool and provide with improved intensity and toughness and traditional WC-Co hard alloy. ;CONSTITUTION: there is a complete solid solution powder powder composition (W, M1, M2, the scale of construction) (C W, M1, M2, the scale of construction) (CN). The solid solution metal (M1, M2, the scale of construction) includes one or more selected from Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and mole % in summation (X-axis) is 0& x =40. A kind of complete solid-solution powder of manufacture comprising steps of mixing carbon dust and being ground metal, metal oxide, carbon dioxide or carbonyl, and heats the mixture, to reduce and be carbonized or reduce and carbonitride. ;The 2012 of copyright KIPO submissions
