Commercial pure titanium; It is a lightweight, biocompatible, high-strength and corrosion-resistant implant material that is widely preferred in dental and orthopedic applications. The aim of this study; It is an attempt to improve the friction and wear properties of the material in order to prevent the high unstable friction coefficients of commercial pure titanium, which is one of the dental implant materials, in contact with metals. For this purpose, NiTi film coatings were applied to Ti substrate samples at different deposition temperatures by RF magnetron sputtering method. The reason for choosing NiTi coatings as coating material; literature review shows that NiTi coatings can convert the applied stress into elastic deformation, give low hardness, high strength, and are biocompatible and sticky on implant materials. After coatings, chemical compositions were determined from the surface of the films using the EDS detector of the Scanning Electron Microscope. X-Ray diffraction measurements of the films deposited at different substrate deposition temperatures were carried out using the XRD device. How the friction coefficient and wear rates of NiTi film coatings are affected by the change in substrate deposition temperatures has been revealed as a result of testing in the nano tribometer wear device.
