The a-C:H (amorphous carbon-hydrogen) films belong to the family of DLC (diamond-like carbon) coatings. The a-C:H coating was deposited on medical grade CoCrMo substrates by plasma-assisted chemical vapor deposition (PA-CVD) using benzene as gaseous precursor. Benzene offers an aromatic structure. which affects the a-C:H properties after plasma decomposition. https://www.lolasalinas.com/
