Researches on improving osseointegration which is defined as a direct bond formation between living bone and implant and reducing bacterial growth on the material, are still among the studies that engage scientists’ attention. While hydroxyapatite coating is one of the most widely used approaches to increase osseointegration, methods used to reduce bacterial growth vary. One of these methods is to form a copper-doped hydroxyapatite layer on the implant, which is known to be antibacterial. In this study, a copper oxide-containing hydroxyapatite thin film layer (HA/CuO) was formed on the surface of 316L stainless steel by using pulsed laser deposition (PLD). Dry sliding wear behaviour and corrosion behaviour of untreated and coated samples were comparatively investigated in PBS (phosphate buffer saline) and SBF (simulated body fluid) after coating. Structural characterizations were examined with SEM and XRD.
