Effects of _-Stabilized Alloying Element on the Nanotube Morphology of Ti-Alloy

Jang S.H., Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

In the present study, we chose Nb as a binary alloying element because it has excellent biocompatibility and be expected to act as a -stabilizer. The purities of the starting raw materials were 99.99% for [...]

Electrochemical Characteristics of Nanotube Formed Ti-Zr Alloy

Kim W.G., Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

In this paper, Ti-Zr(10, 20, 30 and 40 wt%) alloys were prepared by arc melting and nano-structure controlled for 24 hr at 1000 °C in argon atmosphere. Formation of oxide nanotubes are conducted by anodizing [...]

Phenomena of Nanotube Formation on the Surface of Cp-Ti, Ti-6Al-4V, and Ti-Ta alloys

Lee K., Choe H.C., Ko Y.M., Brantley W.A., Chosun University, KR

In this study, the phenomena of nanotube formation on the surface of Ti alloys by electrochemical method. Nanotube layer formed on Ti alloys in 1 M H3PO4 and 1 M H2SO4 electrolyte with small additions [...]

Nanotube Formation and Surface Study of New Ternary Titanium Alloys

Choe H.C., Ko Y.M., Brantley W.A., Chosun University, KR

New titanium alloys with improved biocompatibility have been developed for dental and biomedical applications. The osseointegration of implants depends on surface properties of these alloys; nature of the oxide film at the metal-oxide-bone. Also stress [...]

Nano-Surface Behavior of Osteoblast Cell-Cultured Ti-30(Nb,Ta) with Low Elastic Modulus

Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

Ti and Ti-alloys have good biocompatibility, appropriate mechanical properties and excellent corrosion resistance. However, the widely used Ti-6Al-4V is found to release toxic ions (Al and V) into the body, leading to undesirable long-term effects. [...]

Effects of Zr Content on the Electrochemical Characteristics of Nano-Structure Controlled Ti-alloys

Oh M.Y., Choe H.C., Ko Y.M., Park S-J, Brantley W., Chosun University, KR

Objective: Pure Ti as well as Ti-6Al-4V alloy exhibit excellent properties for dental implant applications. However, for a better biocompatibility it seems important to avoid in the composition the presence of V due to the [...]

Mechanical Properties of Nano-Structure Controlled Ti-Hf Alloy for Dental Implant

Jeong Y.H., Choe H.C., Ko Y.M., Park S-J, Kim D.K., Brantley W., Chosun University, KR

Objectives: Cp-Ti has a excellent biocompatibility. So, it was widely used dental implants and artificial joint. But it is not strong enough for some dental applications. Since Hf belongs to the same group as Ti [...]
