Hydrogenated amorphous carbon (a-C:H) has been considered a promising biocompatible coating to protect metallic alloys against corrosion for medical applications, namely orthodontics. However, there is still no optimal solution this biomedical field; hence, the investigation remains open. In work, effect of nonmetallic doping element (N) on sputter-deposited a-C:H coatings was studied concerning both salivary and cytotoxicity behavior. After 30-day test in an acidic modified Fusayama-Meyer artificial saliva, metal release from coated uncoated 316L stainless steel (SS) substrates quantified. Tests extracts were then performed by using monocultures macrophages fibroblasts, their coculture; cell viability evaluated via MTT test. Results show overall inhibition SS corrosion, which enhanced vitro biocompatibility with minimal coatings’ microstructure. Among all tested, undoped best, whereas increase N led poorer protection dissolution subsequent slightly lower biocompatibility. The findings corroborate that selecting C-based not good choice field, even at low contents up 10 at.%.
