             abstract = "CVD diamond film deposition on WC-Co substrate is the most likely 
                         application of diamond CVD technology towards large scale 
                         production, due to its suitability to aluminium alloys machining 
                         in the automotive and aerospace industry. Several film-substrate 
                         interfaces and surface modifications have been developed aiming 
                         higher levels of simultaneous diamond film-substrate adherence and 
                         substrate surface toughness, however the results are still far 
                         bellow industry requirements for widen scale application. In this 
                         work a new interface is introduced in the CVD diamond films 
                         technology, which consists of a thermo-reactive deposited and 
                         diffused vanadium carbide layer, highly adequate to diamond films 
                         deposition on cemented carbide cutting and forming tools. This 
                         interface presents good diamond growth characteristics, thermal 
                         expansion coefficient similar to the substrate and, in addition, 
                         high hardness and mechanical strength. Diamond films quality and 
                         interface characteristics are evaluated by SEM images and linescan 
                         technique, X ray diffraction and Raman spectroscopy. A typical 
                         Raman shift of 4,1 cm \−1 is obtained observed, 
                         corresponding to a compressive residual stresses of 1,4 GPa 
                         applied from the substrate to the CVD diamond film through 
                         vanadium carbide interface.",
