Technical Abstract: Aqueous starch-oil composites consist of uniformly suspended starch-coated oil droplets (1-10 µm in diameter), and find use in a wide variety of industrial, food, and agricultural applications. One of the main benefits of these starch-oil composites is that they can be drum dried and milled into a dry cake or powder form, and subsequently reconstituted by dispersing them into water. This allows for simple preparation and use in the intended application. Composites of varying starch and oil compositions have been investigated for various lubricant applications, including dry film lubricants for sheet metal forming. Boundary lubrication studies indicate the coefficient of friction for these composites to be a function of the starch-to-oil ratio. However, the mechanism of lubrication is not well understood. This presentation will address and discuss recent investigations into the mechanism of lubrication.
