抜粋

Ti-29Nb-13Ta-4.6Zr (TNTZ) is one of the Ti alloys used for orthodontic wire. However, there is a problem that the metallic color of TNTZ may spoil the appearance of a row of teeth. In previous studies, white oxide coating on disk-shaped TNTZ samples was obtained by heat treatment or atmospheric-pressure plasma (APP) treatment. In this study, the fabrication process of white orthodontic wire by applying APP treatment is proposed. As a result, TNTZ wire which has a white oxide layer with comparable brightness to the surface of Japanese teeth has been successfully fabricated.
