Diamond – like carbon (DLC) thin films are frequently used for coating of implants. The problem of DLC layers lies in bad layer adhesion to metal implants. Chromium is used as a dopant for improvement of adhesion of DLC films. Cr-DLC layers were prepared by a hybrid technology using combination of pulsed laser deposition (PLD) from graphite target and magnetron sputtering (continuous stream of material from Cr target). Atomic concentrations of carbon, oxygen, and chromium were determined from C 1s, O 1s, and Cr 2p photoelectron peak areas. Carbon (sp2 and sp3 bonds) and concentration of trivalent and toxic hexavalent chromium bonds were also determined by XPS.
