BEARING MATERIALS FOR WATER LUBRICATION.

Abstract

Isotactic polybutene in contact with a bronze journal was investigated as a bearing material combination for water lubrication. Aliphatic alcohols were used as model substances for protonic lubricants. The fact that even methanol is a better lubricant than water, in spite of its lower viscosity, is attributed to the lower degree of association. 'Stick-slip' motions indicate boundary lubrication of varying degree. Although polybutene compares favorably with many other organic bearing materials, results of this study indicate that wettability with water is a requirement for further improvement. New bearing material designs for water lubrication are proposed. (Author)
