| Abstract | TiC/a-C :H and a-C :H nanocomposite coatings were prepared on AISI 440C steel substrates using magnetron sputtering process. A comparative study was made on their composition andmicrostructure by Raman spectroscopy and high-resolution transmission electronmicroscopy (HRTEM). The tribological properties of two types of carbon-based coatingswere investigated by pin-on-disc tribometer under the sand-dust conditions concerning the influence of applied load, amount of sand and sand particle sizes. The results show that these carbon-based coatings exhibited high tribological performance with low friction coefficient and wear rate under the sand-dust environments. However, the TiC/a-C :H coatings exhibit relatively higher fluctuant friction coefficient as well as higher wear rate in comparison with the a-C :H coatings under sand-dust environments. The formation of nanocrystalline hard TiC phase distributed in amorphous carbon matrix decreased the residual stress but significantly increased the hardness and Young’s modulus of TiC/a-C :H coatings, and consequently caused a relatively higher abrasive and fatigue wear loss under the sand-dust conditions. |
