Solidification of Boundary Lubricant Films.
Abstract
In this research lauric acid, dodecane, solutions of lauric acid in dodecane and a diester E-105 have been studied in a diamond window high pressure cell. Melting and crystallization behavior were studied as functions of pressure, temperature, time, and solution composition, by means of visual microscopic observation and Fourier Transform infrared spectroscopy. Of greatest immediate significance with respect to the development of improved lubricating fluids, are the experiments in which chemical reactions at a simulated bearing surface were studied by coating the diamond windows with a thin layer of iron. In these experiments the formation of an iron salt of lauric acid was followed by infrared spectroscopy. This work demonstrates conclusively the power of this new experimental technique for studying chemical reactions at interfaces not only of model lubricants but also lubricants and additives of practical interest.
