Cílem této, práce bylo ukázat vliv vlhkosti na opotřebení ncTic/a-C:H povlaku v dynamickém režimu.

The aim of the present work was to study the mechanical properties of ncTiC/a-C:H coating consisting of nanocrystalline titanum carbide embedded in amorphous (hydrogenated) carbon matrix. Combining the properties of hard TiC grains an the softer a-C:H matrix, mechanical properties can be tailored from superhard films with hardness reaching over 40 GPa and Young´s modulus higher than 300 GPa to softer wear resistant and low friction coatings. Magnetron sputtering of titanium target in acetylene containing atmosphere was used for ncTiC/a-C:H preparation. The aim of this work was to study the mechanical and tribological properties of ncTiC/a-C:H coating deposited on high speed steel substrate. Special focus was given on the analysis of the coating resistance against dynamic load under humid environment. The classification of ncTic/a-C:H coatings was performed using an impact tester in a dynamic mode and enabled us to predict the limit load causing the coating destruction under humid environment.
