The paper presents the effect of the complex architecture of Cr/CrN+a-C:H coatings on their mechanical and tribological properties. These advanced coatings were compared with CrN single coatings and Cr/CrN multilayers. All of them were deposited by the magnetron sputtering technique. The conducted tests allowed nanohardness, elasticity modulus, fracture toughness, and adhesion of coatings to steel substrates to be determined. Tribological tests were carried out under dry friction and in the presence of phosphate-buffered saline PBS and foetal bovine serum FBS. For all test conditions, the friction coefficient and the wear index of the produced coatings were determined. The lowest wear and the lowest coefficient of friction are exhibited by coatings with complex Cr/CrN+a-C:H architecture. Furthermore, they are also resistant to the highly corrosive PBS environment.

W pracy analizowano wpływ złożonej architektury powłok Cr/CrN+a-C:H na ich właściwości mechaniczne i tribologiczne. Porównywano je z powłokami pojedynczymi CrN i wielowarstwowymi Cr/CrN, które wytwarzano techniką magnetronowego rozpylania. Przeprowadzone badania umożliwiły określenie twardości, modułu sprężystości, odporności na pękanie i adhezji do podłoża. Testy tribologiczne przeprowadzono w warunkach tarcia suchego oraz w obecności roztworu soli fizjologicznej PBS i surowicy cielęcej FBS. Dla wszystkich warunków tarcia określono współczynnik tarcia oraz odporność na zużycie wytworzonych powłok. Najmniejszym zużyciem oraz najmniejszymi wartościami współczynnika tarcia charakteryzowały się złożone powłoki Cr/CrN+a-C:H. Przy tym są one także odporne na oddziaływanie korozyjne roztworu PBS.
