Titanium and its alloys are widely used in aircraft, rocket production, shipbuilding, machine industry, chemical and food industry, medicine due to their high specific strength, good corrosion resistance and biological passivity. However, titanium has properties which limit its application as construction material. Particularly, tendency to surface adhesion and galling at friction results in it...

Biomedical titanium alloys with Young's moduli close to that of cortical bone, i.e., low Young's modulus titanium alloys, are receiving extensive attentions because of their potential in preventing stress shielding, which usually leads to bone resorption and poor bone remodeling, when implants made of their alloys are used. They are generally β-type titanium alloys composed of non-toxic and all...

Wide use of titanium alloys results from their unique physical and chemical properties 1 . Combination of low density and improved corrosion resistance with good plasticity and mechanical properties determines application of titanium alloys in such industries as aviation, automotive, power and shipbuilding industries or architecture as well as medicine and sports equipment. Despite numerous adv...

Background Nickel-titanium alloy is applied to biomaterials such dental wire, stents and so on, because they have outstanding capacities for corrosion-resistant, adequate mechanical strength and shape-memory [1,2]. On the other hand they have a risk of metal allergy because of leaking nickel ions from them in aqueous conditions. It is not clear the reason why nickel causes allergy and what the ...

New low modulus β-type titanium alloys for biomedical applications are still currently being developed. Strong and enduring β-type titanium alloy with a low Young's modulus are being investigated. A low modulus has been proved to be effective in inhibiting bone atrophy, leading to good bone remodeling in a bone fracture model in the rabbit tibia. Very recently β-type titanium alloys with a self...

The mechanical properties, corrosion resistance and biocompatibility of the titanium-tantalum alloys together with pure titanium are comparatively studied for biomedical applications in this study. The experimental results confirm the previous theoretic investigation that tantalum has a potential to enhance the strength and reduce the elastic modulus of titanium alloys at the same time, and ind...

This paper describes corrosion resistance of titanium and its alloys by introducing a review paper cited from ASM International, Materials Properties Handbook: Titanium Alloys and four examples of practical applications of titanium materials in corrosion protection engineering, which were taken from papers that appeared in the “Special issue on titanium materials” publication of the Japanese la...

INTRODUCTION Titanium alloys are applied as the preferred endplate materials for artificial cervical disc because of their good mechanical properties, prominent biocompatibilities and corrosion resistance [1]. However, the poor tribological performances of titanium alloys might cause aseptic loosening and the osteolysis, which could lead to the failure of the replaced cervical disc implants [2,...

Nb, Ta, and Zr are the favorable nontoxic and allergy-free alloying elements suitable for use in titanium alloys for biomedical applications. Low-rigidity titanium alloys composed of nontoxic and allergy-free elements are receiving considerable attention. The advantage of low-rigidity titanium alloys in the healing of bone fracture and bone remodeling is successfully proven by using tibia of ra...
