Ti6Al7Nb alloys have been widely used in the medical field, particularly in artificial hip joints, spinal fixators, and dental implants, owing to their light weight, low toxicity, and superior corrosion resistance. Grain refinement through a sever...
A customized micro-arc oxidation (MAO) treatment technique was developed to obtain antibacterial properties with no toxicity on Ti surfaces. A two-step MAO treatment was used to fabricate a specimen containing both Ag and Zn in its surface oxide l...
In orthopedics, occasionally, different types of metals are used in applications in which they are in contact with each other. However, few studies have electrochemically investigated the galvanic corrosion of orthopedic implants formed of differe...
Surface and Interface Analysis 54(8) 892-898 2022年8月 [査読有り]
Titanium (Ti) is always covered by thin passive films. Thus, valence band (VB) spectra, obtained using X-ray photoelectron spectroscopy (XPS), are superpositions of the VB spectra of passive films and that of the metallic Ti substrate. In this stu...

Introduction: The next generation surface modification on medical and dental implants is coatings of tissue or stem cells on them.1 To promote cellular attachment and formation of tissues on materials, the control of patterned surface topography i...
Micro-arc oxidation (MAO) was performed on a titanium (Ti) to achieve both hard-tissue compatibility and antibacterial property. The surface oxide layer formed on Ti by MAO treatment in a mixture of calcium glycerophosphate, calcium acetate, and s...
