Abstract
Compositions for treating a substrate to provide increased lubricity to portions of the substrate surface that come into contact with the surface of a mating component are provided. The treated substrates provide improved lubricity, while maintaining adhesion between the surface of the substrate and an overlying polymer coating and imparting corrosion resistance to the substrate surface. The compositions include a silanol coupling agent in combination with lubricating particles, and an acid, which are dissolved or dispersed in a mixture of organic solvent and water.
