Abstract


The influence of diamond deposition temperature in a Hot-Filament Chemical Vapour Deposition (HFCVD) process onto the adhesion of the diamond layer was investigated. The experiments was carried out with 41Cr4 steel, which is standard steel for bearing parts. The partial delamination of the diamond layer is caused by the high compression stresses after cooling of the coated steel substrate. Well adherent diamond coatings was with deposition temperatures between 760°C and 920°C. The influence of the deposition temperature on the residual stresses of the diamond coating was investigated by the Raman spectra. The well adherent diamond coatings showed a higher measured stresses with increasing deposition temperature. It was observed that the transformation of the chromium carbide layer causes a formation of new covalent bonds between chromium carbide and the diamond layer.
