             abstract = "It is well-known that growth and adhesion of polycrystalline 
                         diamond coating directly on steel are both problematic. To solve 
                         these issues, interlayers are needed. For the present study, 
                         diamond film was deposited on steel with intermediate barrier of 
                         silicon carbide (SiC). In addition, laser cladding process 
                         produced interlayer. Diamond films were grown by Hot Filament 
                         Chemical Vapor Deposition (HFCVD). During laser cladding process, 
                         SiC was partially dissociated and so, formation of FeSi was 
                         observed. Just 1-layer SiC was enough to grow diamond film since 
                         the iron is no longer free to migrate to the surface during the 
                         CVD deposition. Nevertheless, the high residual stress formed at 
                         the interface, during the reactor cooling, produces fragmentation 
                         of the diamond film grown with 1-layer SiC on the steel. To 
                         overcome the disadvantage, we propose to create SiC multilayers in 
                         an effort to reduce the influence of steel thermal expansion 
                         coefficient. Detailed characterization of the SiC interlayer, FeSi 
                         phase and diamond coating, are discussed based on X-ray 
                         Diffraction, Scanning Electron Microscopy and Raman Spectroscopy. 
                         Results showed that the presence of FeSi, formed by SiC 
                         dissociation, was the main reason for diffusion barrier 
                         effectiveness. Further, the use of SiC multilayers efficiently 
                         relaxed the high thermal stress.",
