Diamond coating on cemented tungsten carbide(WC-Co)is quite difficult. Generally, to reduce the reactivity of cobalt(Co), which is the binder of WC-Co, an acid pretreatment is applied. Recent reports have described that the adhesion of nanostructured diamond coating was improved using diborane(B2H6)to reduce the reactivity of Co as a catalyst. To obtain boron-doped diamond(BDD), B2H6 and trimethyl boron(B(CH3)3)are often used as boron sources. However, special apparatus must be prepared because of the toxicity, flammability, and explosiveness of these sources.
