The composition of wear-resistant Al/AlC/a-C:H coatings deposited on a magnesium alloy by combination of radio frequency plasma assisted chemical vapor deposition and magnetron sputtering is studied. It is shown that the mechanical properties of the coatings vary depending on the composition of the amorphous C:H layers after changing the negative bias polarization of the process from 150 to 600 V; the carbon structure may be varied from a disordered one to a graphite one as well as the sp2/sp3 bonds ratio.
