W-C:H hard composite coatings were studied. The comparison of the wear rate of the coating/substrate system and the bare substrate obtained from dynamic impact test clearly demonstrated that the coating significantly extended the lifetime of the samples even for high loads and high number of loading cycles. The obtained results will support the research and development of new metal-doped a-C:H coatings, which exhibit promising properties for future engineering applications, especially in dynamically loaded contacts.
