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.
磨损是材料主要的表面失效机制之一，并且在牙科替代生物材料中起着主导作用。本研究的目的是比较牙科应用中不同金属材料的磨料磨损情况。结果表明，基于铂、钯、金和银等贵金属的合金的磨料磨损高于钛及钛基合金。耐磨性最高的合金是钴铬合金，它同时也具有最高的硬度和杨氏模量。由于该方法符合一个成熟的磨料磨损标准，因此可以很容易地比较不同材料的性能。
