This study examined the biocompatibility of the micro-nanoporous layer formed on a titanium-silver (Ti–Ag) alloy. The porous layer was formed by grit-blasting and anodic oxidation. The surface of the porous layer was rougher and more hydrophilic co

The aim of this study was to develop Ti-Ag-Cu alloys with a higher corrosion resistance, better biocompatibility, and better mechanical properties than commercially pure titanium and its alloys. The microstructure, corrosion resistance, mechanical pr

Biometals need high corrosion resistance since metallic implants in the body should be biocompatible and metal ion release should be minimized. In this work, we designed three kinds of super stainless steel and adjusted the alloying elements to obtai

The titanium oxide layer with nano–micro hybrid structure on the titanium substrate was formed by grit-blasting and anodic oxidation treatment. A micro rough surface can be formed by grit-blasting and nanotube arrays can be formed by anodic oxidati

The composition of the electrolytes used in the process of anodic oxidation was modified to generate the novel anodic oxidation. The surface topography of the novel anodic oxidation showed that the pore/crater structures with the precipitants attache

Equiatomic and near-equiatomic nickel-titanium alloys exhibit a shape-memory effect and superelasticity. However, the properties of such alloys are extremely sensitive to the precise nickel-titanium ratio and the addition of alloying elements. High c

Heat treatment is generally applied to orthodontic stainless steel (SS) wires to relieve the stresses that result from their manipulation by orthodontists. The quality and thickness of the oxide films formed on the surface of heat-treated wires can v

Heat treatment is applied to orthodontic wires to inhibit the fracture after the orthodontist manipulates them to make loops, helical springs, and arch forms. We tried to investigate the effect of heat-treatment conditions on the surface properties o
