Abstract

The structure, composition, and mechanical properties of nanostructured titanium carbide (TiC) coatings deposited on H ₁₁ hot-working tool steel by pulsed-DC plasma assisted chemical vapor deposition at three different temperatures are investigated. Nanoindentation and nanoscratch tests are carried out by atomic force microscopy to determine the mechanical properties such as hardness, elastic modulus, surface roughness, and friction coefficient. The nanostructured TiC coatings prepared at 490°C exhibit lower friction coefficient (0.23) than the ones deposited at 470 and 510°C. Increasing the deposition temperature reduces the Young's modulus and hardness. The overall superior mechanical properties such as higher hardness and lower friction coefficient render the coatings deposited at 490°C suitable for wear resistant applications. © 2012 Elsevier Ltd.
