    Abstract

    In this study, the authors investigated the appearance of anomalous film shapes in highly sliding circular contacts when fatty alcohols such as 1-decanol, 1-dodecanol, and 1-tetradecanol were used as lubricants. The film thickness distribution between a steel ball and a glass disc was measured via white-light optical interferometry. The experimental results revealed film thickening under high sliding conditions for all three fatty alcohols. It was observed that for 1-decanol, which has the lowest melting point, the thickened part of the film was the smallest; 1-tetradecanol, which has the highest melting point, produced the largest variation of the film shape.
