To fulfil this challenging goal, the parts of machines are coated with special low friction and high wear resistant materials more and more often. The PVD methods play a great role in this field. As the examples of coatings deposited by a PVD method and assuring the above mentioned goals may serve the nc-CrC/a-C:H and nc-WC/a-C:H.<p><p> This research focuses on the electrochemical and mechanical studies of low friction nc-CrC/a- C:H and nc-WC/a-C:H coatings deposited by magnetron sputtering on two kind of construction materials: Vanadis 23 steel and oxygen hardened Ti-6Al-4V alloy. <p><p>The obtained coatings were investigated using various electrochemical and mechanical methods. The following parameters of coatings were determines: electrochemical (corrosion resistance), micro-mechanical (nanohardness, Young’s modulus) and tribological (wear resistance, friction coefficient). <p><p>The results presented in this paper have been obtained within the project “KomCerMet” (contract no. POIG.01.03.01-00-013/08 with the Polish Ministry of Science and Higher Education) in the framework of the Innovative Economy Operational Programme 2007-2013. ER -
