摘要：
PURPOSE: A method for preparing ultrafine TiC-transition metal-based composite powder is provided to obtain the composite powder having a nanosize suitable to be used in superhard cutting tools. CONSTITUTION: The method for preparing ultrafine TiC-transition metal-based composite powder comprises the steps of: providing a mixed raw material including a Ti-containing material and a transition metal-containing salt, and spray drying the raw material to obtain precursor powder; calcining the precursor powder to form ultrafine Ti-transition metal composite oxide powder; mixing the ultrafine Ti-transition metal composite oxide powder with nano-sized carbon particles and drying the mixture to obtain composite oxide powder; and reducing the dried composite oxide powder under non-oxidative atmosphere, and carrying out carburization and heat treatment.
