Abstract

The influence of several experimental parameters on the sliding-wear behavior of a composite restorative has been examined. The results demonstrate that: 1) Changes in surface finish and sliding velocity have little effect on the moderate wear-rate observed at nominal levels of stress, and 2) increased contact stress can profoundly alter wear mechanisms and produce marked surface failure at levels well within the range associated with human mastication.

摘要

研究了几个实验参数对复合修复材料滑动磨损行为的影响。结果表明:1)表面光洁度和滑动速度的变化对在标称应力水平下观察到的适度磨损率影响很小;2)增加接触应力会深刻改变磨损机制,并在与人类咀嚼相关的范围内的水平下产生明显的表面破坏。
