Method of producing nanophase WC/TiC/Co composite powder

Abstract

The present invention relates to a method of producing nanophase WC/TiC/Co composite powder by means of a mechano-chemical process comprising a combination of mechanical and chemical methods. For this purpose, the present invention provides a method of producing nanophase WC/TiC/Co composite powder, said method comprising as follows: a process of producing an initial powder by means of spray-drying from water-soluble salts containing W, Ti, and Co; a process of heating to remove the salts and moisture contained in the initial powder after spray-drying; a process of mechanically ball-milling to grind oxide powder after removing the salts and moisture therefrom, and to homogeneously mix the powder with an addition of carbon; and a process of heating the powder after milling, for reduction and carburization, in an atmosphere of reductive gas or non-oxidative gas.
