Interactions Between Rolling Oil Emulsions and Aluminum Alloy Surfaces

In oil/water/solid contact angle experiments, aluminum alloy surfaces with a high percentage of MgO in the oxide layer were wetted by naphthenic oil and naphthenic oil containing 1 percent oleic acid. The opposite behavior, poor wetting, was observed on alloy surfaces of almost pure aluminum oxide....

Description
Summary:In oil/water/solid contact angle experiments, aluminum alloy surfaces with a high percentage of MgO in the oxide layer were wetted by naphthenic oil and naphthenic oil containing 1 percent oleic acid. The opposite behavior, poor wetting, was observed on alloy surfaces of almost pure aluminum oxide. On the latter surfaces, however, oil wetting was increased by decreasing the pH and by adding magnesium ions to the water being displaced. The same trends in wetting were observed in interactions between pure oxide powders and a commercial rolling emulsion containing naphthenic oil and oleic acid. The implications of this behavior to process lubrication and surface quality in aluminum rolling are discussed. Presented at the 38th Annual Meeting in Houston, Texas, April 24-28, 1983
