抄録

In continuation of the preceding paper, the wear of metals lubricated by oil, to which a small amount of fatty acid was added,was observed. The results obtained were as follows; (1) The addition of fatty acids to lubricating oils resulted in a remarkable decrease of the coefficient of boundary friction. (2) Saturated fatty acids decreased the coefficient of boundary friction with increasing oil temperature. In the case of unsaturated fatty acids, however, the maximum coefficient value was obtained at 100°C. (3) Fatty acid improved the lubricating properties of oils used below 50°C. On the other hand, when higher temperatures were used, adhesional wear was observed. Saturated fatty acids were more useful than the unsaturated acids for the improvement of the lubricating properties of oils.
