Abstract
In the present study, mechanical alloying (MA) was used to deposit well-bonded TiC coatings on D2 steel sub- strates from titanium and carbon powders. The effect of milling duration and ball-to-powder mass ratio (BPMR), as well as the effect of substrate hardening has been investigated. Microstructure of the coated samples was studied by scanning electron microscopy (SEM). Chemical composition was analyzed by energy dispersive X-ray spectroscopy (EDS). Transmission electron microscopy (TEM)provided evidence for the existence of nano- crystalline coating. Microhardness test was carried out to examine the mechanical properties of the coatings. The coating adhesion strength was evaluated by scratch test. It was shown that a dense and uniform TiC coating with strong bonding to substrate could be formed at the optimal condition (35 h of milling duration, BPMR of 50:1 and hardened substrate). In addition, a possible mechanism was proposed for the formation of TiC coatings during mechanical alloying
