Titanium and its alloys are commonly preferred implant materials for hard tissue applications. Today more than 4.4 million people have an internal fixation device and over 1.3 million people possess an artificial joint. Not only is there high demand for orthopedic surgeries for new patients every year, but there is also an even higher demand for patients who must receive revision surgeries. In order to enhance the properties of titanium based implant materials, different pretreatment and coating techniques are commonly used. Calcium-phosphate coatings are the most favorable method to upgrade the osteointegration properties of biomaterials. Porous structure of hydroxyapatite enables osteoblast attachment, proliferation and finally leads to osteointegration of the implant material. Biological performance of the coated implant can be improved by substitution of various ions. The goal of this study is to reduce implant rejection caused by the human body and increase the implants lifetime as this new generation orthopedic implants are produced. Mimicking the bone structure by coating metallic scaffold with co-doped Hydroxyapatite in effective way enable strong bone-implant integration. The aim is to prepare a new generation of coating on Ti6Al4V implant. Coated plates were evaluated in terms of their mechanical properties.
