Important Modifications of Structures and Properties of WC-Ti-Co Alloys through (Ta, Nb)C Additions

Hard alloys from WC-TiC-Co system are known such as alloys with good wear resistance and high temperature stability in service. (Ta,Nb)C carbide additions improve bending resistance, providing a remarkable corrosion resistance at temperatures of 800°C. The researches and the results presented in this paper lead to conclusion that (Ta,Nb)C additions in WC-TiC-Co alloys are very important and must be considered.
