Based on recent studies, mechanical and tribological properties such as hardness, Young's modulus, friction, and scratch adhesion strength on various coatings and ultra-thin films are reported. These results were obtained using a Universal Nano+Micro Tester UNMT-1, suitably designed for comprehensive evaluation of mechanical and tribological properties of bulk materials, coatings and thin films. Results indicate that a substrate effect for ultra-thin films is substantial when using conventional static nanoindentation technique, while negligible with an advanced dynamic nano-indentation. Comparative results of hardness and Young's modulus obtained from various techniques are presented. Also, a means to evaluate friction and adhesion strength of thin films is highlighted, using DLC specimens as an example.
