磨损是材料表面失效的主要机制之一，在牙科生物材料替代品中将发挥主导作用。本研究的目的是比较牙科应用中使用的不同金属材料的磨料磨损。结果表明，Pt、Pd、Au、Ag等贵金属基合金的磨粒磨损率高于Ti和Ti基合金。具有最高耐磨性的合金是Co-Cr，其也表现出最高的硬度和杨氏模量。由于该方法对应于一个完善的磨料磨损标准，不同材料的行为可以很容易地进行比较。
Wear is one of the main surface failure mechanisms in materials and it will play a leading role in substitutive dental biomaterials. The aim of the present study is to compare the abrasive wear of different metallic materials used in dental applications. The results show that the abrasive wear of alloys based on precious metals such as Pt, Pd, Au and Ag is higher than for Ti and Ti based alloys. The alloy with the highest wear resistance is the Co-Cr which exhibits as well the highest hardness and Young's modulus. Since the method corresponds to a well-established abrasive wear standard, the behaviour of the different materials can be easily compared.
