comparison of the corrosion behavior of Pure Titanium and its alloys in fluoride containing sulfuric acid
Corrosion Science, 2016Co-Authors: Zhen Wang, H X Hu, Yong Zheng, Wei Ke, Yanxin QiaoAbstract:Abstract The corrosion behavior of Pure Titanium, Ti-0.2Pd and Ti-0.3Mo-0.8Ni alloy in fluoride-containing sulfuric acid were investigated using electrochemical methods combined with surface characterization. The results showed that Titanium alloys exhibited higher corrosion resistance than Pure Titanium at fluoride concentrations lower than 0.002 M due to the acceleration effects of Pd and Ni on cathodic process and the inhibition effect of Mo on anodic process. But Titanium alloys are still corroded as severely as Pure Titanium at higher fluoride concentrations. The influences of alloying elements on the corrosion behavior at different fluoride concentrations were well explained using the mixed potential theory.

dental implant materials commercially Pure Titanium and Titanium alloys
Journal of Prosthodontics, 1999Co-Authors: Msbe Michael MccrackenAbstract:Manufacturers use six different Titanium-based biomaterials to fabricate dental implants. Each of these materials, including four grades of commercially Pure Titanium and two Titanium alloys, has distinct mechanical and physical properties. Clinicians should recognize these differences for optimal treatment planning and patient care.

Multi-Stage Cold Deep Drawing of Pure Titanium Square Cup
Key Engineering Materials, 2015Co-Authors: Yasunori Harada, Minoru UeyamaAbstract:This paper deals with the formability of Pure Titanium sheet in square cup deep drawing. Pure Titanium has very excellent corrosion resistance. In the metal forming process, Pure Titanium has very good ductility in cold forming. The normal anisotropy of Pure Titanium is very high. Therefore, the property is suitable to the sheet metal forming, such as deep drawing process. However, the most important problem is that the occurrence of seizure becomes remarkable in severe forming operations. Many investigations on the effect of processing conditions on the seizure of Titanium were carried out. In the present study, the formability of Pure Titanium sheet in square cup deep drawing was investigated. For the prevention, Pure Titanium sheets were treated by heat oxide coating. The fresh and clean Titanium is not in direct contact with the die during the forming due to the existence of the oxide layer. The material was Pure Titanium sheets of the JIS grade 2. The initial thickness of the blank was 0.5 mm in thickness. In the deep drawing process, the sheets were employed and a flat sheet blank is formed into a square by a punch. Forming of sheet by multi-stage deep drawing was tried. Various cups were drawn by exchanging the punch and die. The die was taper without a blankholder in the subsequent stages. The effects of the intermediate annealing and tool shape on the occurrence of seizure in square cup deep drawing were also examined. The square cups were successfully drawn by heat oxide coating. The coating of Titanium sheet has sufficient ability in preventing the seizure in multi-stage deep drawing operation. The results of the present study revealed that the Pure Titanium square cups were successfully formed by using heat oxide coating treatment.

Procedia Engineering, 2014Co-Authors: Yasunori Harada, Minoru UeyamaAbstract:Abstract Aiming to expand the use of the product, the formability of Pure Titanium sheet by square cup deep drawing was investigated. Forming of Titanium sheet was tried by multistage deep drawing. In the experiment, the material was Pure Titanium sheets of the JIS grade 2.

Various cups were drawn by exchanging the punch and die. The die was taper without a blankholder in the subsequent stages. For the prevention, Pure Titanium sheets were treated by heat oxide coating. The fresh and clean Titanium is not in direct contact with the die during the forming due to the existence of the oxide layer. The effect of the plastic anisotropic on the occurrence of seizure in square cup deep drawing was also examined. The square cups were successfully drawn by heat oxide coating. The coating of Titanium sheet has sufficient ability in preventing the seizure in multistage deep drawing operation. It was found that the square Pure Titanium cups were successfully formed by using heat oxide coating treatment.
