Abstract

The microstructure, mechanical properties, and corrosion behavior of binary Ti-xPt alloys containing 5, 10, 15 and 20 wt% Pt were investigated in order to develop new Ti-based dental materials possessing superior properties than those of commercially pure titanium (cp-Ti). All of the Ti-xPt (x = 5, 10, 15, 20) alloys showed hexagonal α-Ti structure with cubic Ti₃Pt intermetallic phase. The mechanical properties and corrosion behavior of Ti-xPt alloys were sensitive to the Pt content. The addition of Pt contributed to hardening of cp-Ti and to improving its oxidation resistance. Electrochemical results showed that the Ti-xPt alloys exhibited superior corrosion resistance than that of cp-Ti.

摘要

研究了含5%、10%、15%和20%（重量）铂的二元Ti-xPt合金的微观结构、力学性能和腐蚀行为，以开发出性能优于商业纯钛（cp-Ti）的新型钛基牙科材料。所有Ti-xPt（x = 5、10、15、20）合金均呈现出具有立方Ti₃Pt金属间相的六方α-Ti结构。Ti-xPt合金的力学性能和腐蚀行为对铂含量敏感。铂的添加有助于cp-Ti的硬化并提高其抗氧化性。电化学结果表明，Ti-xPt合金表现出比cp-Ti更好的耐腐蚀性。
