In this study, Cu–Mo composite coatings were produced on copper substrate by plasma spray technique. Electrical conductivity and microstructure properties of the composite coatings were investigated. Microstructure and phase composition of the coatings were examined by using optical microscopy (OM), scanning electron microscope (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDS). The microhardness experiments were also performed by using a microhardness machine. The electrical conductivity properties of the coatings were evaluated with eddy current instruments. Although the electrical conductivities of the coatings are very small compared to the substrate, it has been determined that the coatings exhibit a very good hardness values in comparison to the substrate.

After the implantation of a biomaterial, it is exposed to mechanical loads and body fluids continuously or periodically according to the implantation area. Hence, the most important expectancy of biomaterials is to be biocompatible; not to cause a reaction or impede natural growth of the tissue, bone and organ. Ceramic materials with excellent mechanical, corrosion and abrasion resistance is set in terms of features such as biomaterials. In this study, ceramic coatings were produced on AISI 316L stainless steel by the plasma spray method. It was aimed to investigate microstructure and biocompatibility properties of coatings. Scanning electron microscope (SEM) analysis and X-ray diffraction (XRD) phase analysis were used to determine the microstructure and phase composition properties. The biocompatibility properties of coatings have been tried to be determined by analysing cytotoxicity and viability.
