Abstract

The mechanical properties and friction and wear characteristics of titanium-containing amorphous hydrocarbon (Ti-C:H) nanocomposite coatings were investigated. The hardness and elastic modulus of the coatings showed smooth variations with increasing Ti composition. Bimodal friction and wear behaviors for TiC/a-C:H nanocomposites were revealed by the results. It was found that coating wear mechanism changed as the TiC cluster volume fraction increased beyond the percolation threshold.
