1. Synthesis of Vanadium Interface for HFCVD Diamond Deposition on Steel Surface
Laser cladding of vanadium carbide powder developed an interlayer on AISI D6 steel as a diffusional barrier and to relief thermal residual stress. Laser cladding experiments varied resolution (DPI) and scanning speed (mm/s). CVD diamond deposition on this interface went on by HFCVD technique. The coatings were characterized by X-ray diffraction analysis (XRD

2. Estudos da deposição de filmes de diamante CVD sobre carbeto de tungstênio, com interface controlada de boreto / Studies of the deposition of diamond CVD films on tungsten carbide, boride with interface control
The objective of this work was to obtain adherent diamond films on WC-Co substrate through the hot filament assisted CVD technique, using a boriding process to form an intermediate layer and avoid the diffusion of the cobalt to the substrate surface. The boriding process consists of a reactive thermo diffusion treatment, in which boron atoms are spread in th
