Localized wear tests have been performed on six resin composites using a recently developed three-body wear testing machine. After repeated loading to the composites, the worn surface was replicated. Then the wear values of the respective resin composites were determined from the surface area of the worn defect using an image-analyzer. In addition, the microstructure of the worn area was analyzed with a scanning electron microscope (SEM). This study revealed that a fine particle hybrid composite exhibited the greatest localized wear resistance of all resin composites investigated in this study. SEM of the microfilled resin composites showed some degradation between filler and matrix.
使用最近开发的三体磨损试验机对六种树脂复合材料进行了局部磨损测试。在对复合材料进行反复加载后，复制磨损表面。然后使用图像分析仪根据磨损缺陷的表面积确定各树脂复合材料的磨损值。此外，用扫描电子显微镜（SEM）分析磨损区域的微观结构。本研究表明，在本研究中所研究的所有树脂复合材料中，细颗粒混杂复合材料表现出最大的局部耐磨性。微填料树脂复合材料的扫描电子显微镜显示填料和基体之间存在一些降解。
