The relation between the preferred orientation, microhardness, and microstructure of TiC coatings was studied for various deposition conditions. The coatings deposited at 1000 °C showed 〈111〉 preferred orientation and finer equiaxed grains, resulting in high microhardness values. High microhardness values were also obtained with a decrease in total pressure. Coatings deposited above 1100 °C showed 〈110〉 preferred orientation and coarser elongated grains which results in lower microhardness values.
