The procedure of Cr‐DLC coating deposition using a hybrid ARC‐MAG‐RF PACVD method is presented in this paper. ARC and MAG techniques were used to deposit a Cr/Cr‐C:H interlayer with increasing hardness, but a nearly constant elastic modulus of the value similar to a steel substrate and DLC layer deposited then by RF PACVD technique. As a result of such coating formation the lower level of stresses in the coating‐substrate system, both intrinsic and induced by the load applied, was obtained. The resultant Cr‐DLC coating is marked by high crack resistance and high adhesion. The Cr‐DLC coating shows high wear resistance, but the wear geometry and the friction coefficient depend on a type of the counterpart material.
