| Outline of Final Research Achievements |
The purposes of this research are "establishment of information acquisition/evaluation method for surface texture" and "establishment of in-situ detection method for friction/wear transition". Therefore, an image measurement system that can be easily installed on many objects was created. Using this system, laser reflected light of samples with different surface textures was acquired as a scattered light image. The characteristic values of these acquired images were evaluated by the digital image processing. As a result, it was found that the laser reflected light measurement of the surface texture is useful as a basic evaluation technique of the sample surface state assuming frictional motion.

本研究によって、すべり面の表面性状をそのレーザ反射光情報を取得して評価できる基礎技術は確立した。この技術の高精度化および応用することで、摩擦力や摩耗量の測定結果を使用しない状態遷移評価と無潤滑すべり面の状態監視評価が可能となることが予想される。さらに、状態遷移判定に経験やノウハウが不要となり、検査コストの削減も想定される。本研究成果はこれらの機械要素に関連する複雑な問題解決の基礎技術であるため、学術的・社会的意義がある。
