Machine Design and Tribology

In order to realize a carbon-neutral or decarbonized society, mechanical systems are required to be highly efficient, lightweight, and have a low environmental impact. At the mechanical design laboratory, we apply cutting-edge surface modification methods, coating methods and analysis methods to study technologies that dramatically improve the life, efficiency, and functionality of power transmission elements for EVs and various tribo-elements.

Development of water lubrication coating: Water lubrication technology is expected as an alternative technology to oil lubrication with the aim of reducing environmental impact. In this study, we study the creation of new coatings that exhibit ultra-low friction with a friction coefficient of 0.01 in aqueous solutions such as water and seawater and the elucidation of their water-lubrication mechanisms. This study aims to apply not only to machines but also to artificial joints.
