Biomaterials, which are increasingly bioactive, reliable and effective, are materials used to perform or support the functions of organs or living tissues in the human body and are constantly or at certain intervals in contact with body fluids. The most important feature is biocompatibility, and they can be studied in two ways: structural and surface compatibility. The surface compatibility is that a biomalcemic is physically, chemically and biologically suitable for the body tissues. Structural compatibility is the optimal compatibility that the material provides to the mechanical behavior of the body tissues. Titanium and alloys are one of the best materials for biomedical ortopedic implant applications due to their high mechanical properties, low elasticity module, high corrosion resistance and excellent body compatibility. In another group of materials used as hard tissue implants, calcium phosphate materials are a ceramic that forms the inorganic structure of the bone, tooth and tooth minus tissue, and is used in the production of various proteins as artificial bone due to its biocompatibility, in the repair of broken and broken bones and in the covering of metallic biomaterials. In this study, as a source of calcium, calcium chloride dihydrate (CaCl2 H2O) was expanded on the surface of calcium phosphate titanium with the technique SILAR (Successive Ionic Layer Adsorption and Reaction) using tri sodium phosphate (Na3PO4 12H2O) as a source of phosphate. Pre-covering purely titanium surface is applied and passivization process with nitric acid and distillated water is made. The method of immersion on the titanium substrate is covered in uniform thickness layer. Calcium phosphate accumulated on titanium has been studied, scanned electron microscope(SEM), X-work breakdown(XRD), tribolological and electrochemical properties.
