Characteristics of sliding friction at low temperatures ranging from +20℃ to -50℃ are obtained under dry and thin-film conditions. The temperature of the test pieces is lowered with dry ice at the back of the plate, and both the plate and the slider are enclosed in a small chamber in which air of extremely low humidity is feeded. The dry kinetic friction is found to decrease, in general, slightly with the fall of temperature so far as the surface of the plate is kept from water moisture, but when the water moisture is present and the trace of frost appears on the surface at some temperature under zero degree, friction falls conspicuously. It is found also that when the surface is lubricated with mineral oil, stick-slip disappears. at some critical temperature which corresponds to the freezing point of the oil. For butyric acid which shows no orientation at room temperature also appears this critical point at low temperature and it is found to be about -5.5℃ for the combination of Cu slider and Cu plate.
