Investigations of Titanium Implants Covered with Hydroxyapatite Layer

To reduce unfavorable phenomena occurring after introducing an implant into human body various modifications of the surface are suggested. Such modifications may have significant impact on biocompatibility of metallic materials. The titanium and it's alloys are commonly used for joint and dental implants due to their high endurance, low plasticity modulus, good corrosion resistance as well as biocompatibility. Special attention should be given to titanium alloys containing zirconium, tantalum and niobium elements. These new generation alloys are used by worldwide engineering specialists. The experiments were performed with hydroxyapatite layer on titanium specimens with the use of electrophoresis method (different voltage and time).
