| Abstract: | This paper investigates the surface reaction of diamond with cobalt-based bond materialsduring hot pressing.The results show that the bonding behavior of bond materials on diamond isdependent on the resultants of chemical reaction formed as the bond- diamond interface to a largeextent. During hot pressing , the carbide-forming elements(titanium and chromium) react withdiamond to form a carbide layer and this layer results in having metallurgical combination be-tween bond materials and diamond. The relative bending tests of cobalt- based bond with carbide-forming elements confirm that the carbide-forming elements increase the bonding strength ofbond matrixes to diamond. |
