Hot Hardness of WC-Co/TiC-Al2O3 Composite Materials.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2002 WC particle was coated with TiC and Al2O3 particles using Co binding one by means of high-speed rotational blending to enhance the degree of mixing. Then the sintered composite material of WC-Co/TiC-Al2O3 was prepared, and the hot hardness was measured up to 800°C to be compared with conventional WC-Co alloy.
