114 アルミニウム合金に対する生分解性油の摩擦・摩耗特性

抄録

Tribological properties were studied for rapeseed oil, polyolesters and mineral oil with an aluminum alloy in on disk type tribometer, by which the wear amount, the coefficient of friction and the contact potential relating to the formation of boundary film could be simultaneously detected during the run. For rapeseed oil the friction behavior was high with irregular fluctuation and the wear amount drastically increased during the run. On the other hand, the coefficient of friction for polyolesters was low level throughout the run, and the initial wear behavior followed by wear in the steady state was observed.
