Abstract:Through investigation on composition, microstructure and mechanical properties of foreign surgical implant and domestic product, it is found that domestic product has the same nature with the foreign surgical implant, but there are variations of stability in quality, composition, microstructure and properties. Through the development in recent years, effective control measures for composition, microstructure and properties of surgical implants were obtained by Xi’an Saite Metal Material Co., Ltd., to provide high-quality products for surgical implants.
Key words: Ti6Al4V; surgical implant; bar; microstructure; mechanical properties
