Titanium Alloys for Spinal Fixation Devices

Titanium Alloys

Although originally discovered in the 18th century [1], the titanium industry did not experience any significant advancement until the middle of the 20th century through the development of the gas turbine engine [2]. Since then, the aerospace sector has dominated worldwide titanium use with applications in both engines and airframe structures [3]. The highly desirable combination of properties,...

Titanium and Titanium Alloys as Biomaterials

Titanium Alloys in Orthopaedics

Metallic implants are commonly used in the orthopedic field. Despite the large number of metallic medical devices in use today, they are predominantly make up of only a few metals. Metallic alloys such as titanium continue to be one of the most important components used in orthopaedic implant devices due to favorable properties of high strength, rigidity, fracture toughness and their reliable m...

A Novel Surface Treatment for Titanium Alloys

High-speed commercial aircraft require a surface treatment for titanium (Ti) alloy that is both environmentally safe and durable under the conditions of supersonic flight. A number of pretreatment procedures for Ti alloy requiring multi-stages have been developed to produce a stable surface. Among the stages are, degreasing, mechanical abrasion, chemical etching, and electrochemical anodizing. ...

Casting of Titanium Alloys for Dental Applications

In dentistry, gold-based noble metal alloys have traditionally been cast into various types of dental prostheses, such as partial dentures, crowns, and bridges. More recently, less expensive dental alloys with base-metal elements, such as Co-Cr and Ni-Cr, have been used. Titanium is considered to be an attractive alternative to these traditional dental alloys because of its remarkable lack of t...
