| Outline of Final Research Achievements |
The objective of this study is to develop an in situ observation system for frictional areas that could capture at a high frame rate for long time. The developed observation system is used for observing instantaneous phenomena such as wear debris generation, plastic flow behavior and occurrence of scuffing.
The developed observation system comprises of four CCD camera and flashing light. The observation system controls independently the capturing timing of each camera to succeed in increasing the frame rate of four capturing images.
Plastic flow behavior during scuffing can clearly be observed by the present observation system. The plastic flow speed increased with increasing sliding speed. However, the plastic flow speed was more than one-digit smaller than the sliding speed.
