Introduction316L Stainless Steel has been selected as a substrate with excellent corrosion resistivity, oxidation resistance, and high deflection strength. However, Stainless Steelimplanted in the body, may release various ions such as nickel, chromium and iron from it in tissue that cause sensitization and tissue stimulation. Implants need antibacterial properties, but 316L does not have this properties. To overcome this challenge, polymeric, ceramic or composite coatings have been developed. Baghdadite has been considered as a bioactive bioceramic with excellent biocompatibility, good mechanical properties, and the ability to stimulate bone growth. In another word, chitosan is a biopolymer with antibactrial activity, excellent biocompatibility and good biodegradability. ObjectivesThe purpose of this study was to fabricate chitosan / Baghdadite nanocomposite coating on 316L stainless steel using electrophoretic technique and study the role of Baghdadite on the improvement of bioactivity and biocompatibility of materials used in the body.ResultsResults showed that incorporation of Baghdadite significantly improves the biological properties of composite coating and made them promising for implant materials
