摘要

针对临床上对口腔用植入材料的要求以及现有医用钛合金存在的问题

以Ti-Zr合金系为基础

设计了以Mo、Sn、La为添加元素的口腔用Ti-Zr-（M）多元合金

同时利用DX2000型X射线衍射仪、4XC倒置金相显微镜、HV-50A型维氏硬度计、M-200型磨损试验机

讨论热处理对其物相、显微组织以及力学性能的影响。结果表明

经热处理后

合金的硬度稍微下降

耐磨性显著提高

这是由于Sn、La添加元素主要对α相起固溶强化作用

稳定α相;Mo对β相起稳定作用

有利于β相的形成

使该合金系更能满足口腔植入材料对生物相容性和耐磨的要求。

Abstract

Aiming at the clinical requirements for medical titanium alloy and its existing problems

a new kind of oral Ti-Zr-（M） titanium alloy was designed through adding Mo

La into Ti-Zr alloy system. Effects of heat treatment on phase constituent

microstructure and mechanical properties of the alloy were investigated by DX2000-X-ray diffractive instrument

4XC upside-down metallography

HV-50A sclerometer and M-200 abrasive machine. The results indicate that hardness of the annealed alloy is slightly decreased with the great improvement of wear resistance

which is attributed to Sn and La stablizing α phase and plays a role in solid solution strengthening effects and Mo being beneficial to the formation of β phase

meeting the requirements of biologic compatibility and wear resistance for oral Ti alloy materials.
