The kinetic frictions of lubricated surfaces of solids were measured and the differences in the friction between low energy surfaces like fibres and high energy surfaces like metals were investigated. Straight-chain fatty acids and these copper soaps were employed as lubricants.
If new lubricant is not formed on the lubricated surface by the reaction of the lubricant with the surface of the solid, the chemical property of the surface has the following influences on the friction:
1. When a good lubricant that has long enough chain length is employed, the property of the surface has no influence.
2. When a poor lubricant that has short chain length is employed, the lubrication of fibres is more difficult than that of metals. And the friction of poorly lubricated fibres is higher than that of metals.
