| Research Abstract |
The aim of this study was to develop a new method for synthesizing hard rare earth metal oxide films of scandium, yttrium, lanthanum, cerium, plaseodymium and neodymium and to investigate their mechanical and tribological characteristics. Oxide films of scandium and cerium showed low friction and/or low wear. Since the present synthesis enables coating of 4 sheets of tatami with a thickness of 50nm from merely1g of scandium, engineering as well as industrial application is anticipated.
