| Resumo | Vanadium carbide has been used in the industry to improve the steel properties. It was extensively studied and explored by Toyota a few decades ago. Vanadium has high hardness, as well as carbides forming ability, chemical compatibility with carbon steel and CVD diamond and an intermediate thermal expansion coefficient (TEC) between these materials. These characteristics make vanadium carbide attractive as an intermediate layer for CVD diamond applications. There are many techniques to obtain a vanadium carbide interface such as thermodiffusion and sputtering. In this work, we will discuss the vanadium carbide deposition by laser cladding on carbon steel surface. The main problems in growing CVD diamond directly on steel surface are related crystallinity, purity and adhesion. The crystallinity issue is due to the fact that the gas phase carbon goes in to the steel substrate bulk causing its embrittlement and reducing diamond growth rate. The problem regarding purity is related to the transitions metals present in the steel surface (such as iron and cobalt) that inhibit the sp3 bond over the sp2 bond, providing the appearance of graphite on CVD film that reduces the film quality. As for the Adhesion challenge, the TEC mismatch results in a high residual compressive tension in the diamond film, which causes delamination during cooling. Therefore, an intermediate layer is necessary to create a transition zone able to relieve the thermal residual stress and also to act as a diffusional barrier. The laser cladding was selected because of its rapid processing, excellent metals adhesion by melting, good surface finish reducing roughness and capacity to preserve the original properties of the material substrate interacting only with the up layers of the material. In this study, we analyze vanadium carbide phase formation by varying systematically the following parameters: resolution (300 900 DPI); scanning speed (100 500 mm/s); and output power (40 125 W). For the substrate we used AISI D6, AISI O1 and AISI M2 steels. The HFCVD films were grown using the following parameters: 2 sscm of CH4; 98sccm of H2; 2h deposition process time; 700°C and 5mm of work distance. The results of LCVC coating and HFCVD films characterizations were obtained by X-ray diffraction, scanning electron microscope field emission (SEM-FEG) and Raman spectroscopy. | |||
