Patent ID: 7217390

Claim:
A fabrication method of an ultra-fine TiC-base cermet alloy with a homogenous solid solution grain structure comprising the steps of: forming powder mixture of TiC 50–90 wt % (weight percentage), TMxCy (where x and y are integers) 5–30 wt % and Ni or Co or a mixture of Ni and Co 5–30 wt % from mixing titanium (Ti) powder, transition metal (TM) powder, carbon (C) powder and nickel (Ni) powder or cobalt (Co) powder or both Ni powder and Co powder; synthesizing a nano-composite powder of (Ti, TM)C—(Ni, Co) through a high energy ball-milling of previously said powder mixture by putting into a milling jar together with balls with a fixed diameter; and compacting and sintering said synthesized composite powder.
