Hydrogen Equipment Tribology Lab
Machine-translated · View original
The tribology lab studies friction, wear, and lubrication, including in hydrogen environments.
AboutAbout the lab
Unraveling the phenomena of friction, wear, and lubrication
The Tribology Lab specializes in tribology, the field that deals with problems of friction, wear, and lubrication.
Working with universities, research institutes, and companies in Japan and abroad, the lab tackles both fundamental issues, such as exploring and clarifying the various phenomena that occur at friction surfaces, and applied issues, such as solving practical problems.
The lab also studies tribological properties in hydrogen atmospheres.
Assistant Professor Hiroyoshi Tanaka aims to improve the performance of machine elements, focusing on rolling contact fatigue of bearings and DLC coatings.
Key terms
- Tribology
- The field of study that deals with problems of friction, wear, and lubrication
- Rolling contact fatigue
- A phenomenon in which rolling contact parts such as bearings are damaged by repeated loading; it determines the durability of machines
