초록

Unique tooth-like (milky white) color ${\beta}$-Ti dental arch wires are prepared by anodization in a 1M $H_2SO_4$ electrolyte at $30^{\circ}C$ and 30 V for 88 min and 40 s. Aggregates are formed on these surfaces of the anodized wires with tooth-like colors, and the results are different from those of the anodized wires with monochromatic colors which have smooth oxide surfaces. Similar to the monochromatic wires, the composition of the oxide layer is $TiO_{2-x}$ and the x approaches zero at the outer layer. But different from the amorphous structure observed in monochromatic wires, the oxide layers are partially crystallized with an anatase structure. The milky white colors result from the rough and crystalized oxide layers, not by the interference effect as observed in monochromatic wires.
