The fracture and fatigue characteristics of several cemented carbide grades are investigated as a function of their microstructure. In doing so, the influence of binder chemical nature and content (Co and 76wt%Co-24wt%Ni), as well as carbide grain size on hardness, flexural strength, fracture toughness and fatigue crack growth (FCG) behavior is evaluated. Mechanical testing is combined with a d...

Advantages  Technology allows for improved diamond deposition process, which results in stronger adhesion.  Improved adhesion of the film produces lower stresses to thereby increase the drill lifetime.  When compared to untreated drill bit, our drill bit was able to drill over 100 holes, whereas the untreated only drilled 40 holes before breaking. o Increased durability over 50% Diamond film...
