Through joint research with the U.S. Geological Survey and the University of Tokyo, NIMS for the first time experimentally demonstrated friction completely independent of sliding velocity—an ideal that had never been realized—by heating mica, a layered oxide also used as a lubricant material, to 200°C (392°F). NIMS also clarified that this is caused by the disappearance of defects within crystals at high temperatures.
Heating mica to 200°C reveals friction independent of sliding speed
Joint research by NIMS, the U.S. Geological Survey, and the University of Tokyo demonstrated friction independent of sliding velocity by heating mica to 200°C. This breakthrough reveals insights into material properties that could influence various applications, including those relevant to Iran's industrial sectors.
👥 Key Players
📰 What Happened
Joint research demonstrated that heating mica to 200°C can create friction that is independent of sliding velocity. This finding is a significant breakthrough in understanding material properties.
- Friction independent of sliding velocity was experimentally demonstrated for the first time.
- The phenomenon is linked to the disappearance of defects within mica crystals at high temperatures.
💡 Why It Matters
📚 Background
Mica is a mineral commonly used in lubricants and other industrial applications. Understanding its properties at different temperatures can lead to better material performance.
