Tribological Heritage Research Committee (The 1st category)

The purpose of this research committee is to make a record of technical advances in the field of tribology and deepen knowledge related to the history of tribology while also pursuing activities to foster the general public’s understanding regarding this field. For that purpose, we began in 2007 to investigate tribological heritages and preserve and register various types of materials in order to promote broader general interest and understanding concerning this field. In 2008, with the cooperation of Japanese Society of Tribologists member companies, we plan to conduct surveys regarding tribological heritages, carry out heritage registration and certification work, and investigate museums, reference rooms, exhibition rooms, etc. in order to grasp the current situation.

Ionic liquids for tribology: fundamental & applications (The 3rd category)

Ionic liquids are unique compounds that possess thermal stability, non-flammability, non-volatility and high thermal capacity. These properties are desirable for advanced lubricants. In fact, the tribological properties of various ionic liquids have been acquired in laboratory and have been reported. Plenty types of cations and several types of anions are known to be precursors of ionic liquids. Possibility of ionic liquids, prepared by combining anion and cation, is estimated more than one million. Therefore systematic research is required to reveal the tribology of ionic liquids. Our research consortium aims to share the technical information regarding the tribology of ionic liquids obtained from the public domain. We welcome any tribologists who are interested in ionic liquids; of course both academic researchers and industrial engineers. For details, do not hesitate to ask us by e-mail
