The application of various coatings on traditional material substrata (e.g. metal alloys) is a well established technology used to modify surface characteristics/performances of various components in technical systems exposed to adverse conditions, e.g. corrosive environment, high temperature, erosion and/or wear, etc. [1… 10]. Coatings can also provide a desired (mostly low) friction coefficient between solids forming various tribological systems. In recent years there has been a particular increase in interest in carbon-based coatings, either crystaline (diamond or graphite) or amorphous. This applies especially to amorphous carbon with high content of sp3 bonds characteristic of the diamond - known as DLC (diamond-like carbon). This coating can be "pure" form of DLC, if it contains only sp3 bonded carbon, but may also contain other elements and crystalline structures; Hydrogen, carbon with the "graphite" sp2 bonds, metals and/or other modifiers, which can provide the required specific properties of the coating and reduce the cost of production.
