             abstract = "The union of the unique diamond properties with steel (most common 
                         substrate material) provides a new solution for machine parts 
                         under critical mechanical conditions and severe environmental. 
                         However, CVD diamond coating directly on steel comes with several 
                         issues. The fundamental reasons for the lack of adhesion are an 
                         iron catalytic effect, the high carbon solubility in iron and high 
                         mismatch in thermal expansion coefficient of diamond and steel. 
                         The use of interlayer may solve these issues acting as a diffusion 
                         barrier, for both iron and carbon, and match thermal expansion 
                         coefficients. Several articles describe the PVD deposition or 
                         electroplated interlayer. In the present study, the diamond film 
                         coated steel with an intermediate barrier deposited by laser 
                         cladding process. In this novel technique, laser irradiation melts 
                         the powder (preplaced) and the substrate surface to create the 
                         coating on a steel substrate. We used the SiC/Ti and SiC/Cu powder 
                         mixtures to create the intermediate barrier. Diamond film 
                         deposition was carried out in an HFCVD reactor (Hot Filament 
                         Chemical Vapor Deposition). The samples characterization included 
                         X-ray Diffraction (XRD); Field Emission Gun - Scanning Electron 
                         Microscopy (FEG-SEM) and Raman Scattering Spectroscopy (RSS). 
                         Results showed that laser incidence dissociated partially the SiC 
                         powder, forming FeSi, Cu3Si phases. Further, the composite layer 
                         assisted the high thermal stress relief in steel/diamond 
                         interface.",
