Coatings for metallic biomaterials

摘要: Abstract: Titanium and its alloys show the greatest biocompatibility among metallic materials for biomedical applications. They are, however, grouped within bioinert together with ceramics, such as alumina zirconia, on basis of pattern osteogenesis. For tight fixation long-term use, some applications need bioactivity, which means an ability to make a bond directly natural bone. Calcium phosphate-based ceramic materials, hydroxyapatite, tricalcium phosphate so on, are often coated onto biomaterials. In this chapter, recent topics concerning bioactive coatings biomaterials briefly reviewed. New types coating methods titanium alloys, including plasma-spraying forming highly oriented sputtering or vapor-deposition inducing excellent bioactivity glass-ceramic joining, focused upon, well chemical modifications their surfaces.
