A process for producing an enhanced friction reducing surface by bonding a dry lubricant to a substrate by way of high velocity mechanical impact and low temperature diffusion bonding, and the friction-reduced surface produced thereby. Kinetic energy produced from the mechanical impact drives the lubricant against the surface of the substrate, forming a metallurgical bond between the lubricant and the substrate surface. Performance of a subsequent low temperature solid state diffusion bonding step at less than half the melting point of the substrate causes, in combination with the stored bond energy, causes the lubricant to penetrate into the sub-surface of the substrate. The resulting substrate, modified at the sub-surface level but without any loss of metallurgical characteristics, demonstrates significantly improved wear and friction-reducing characteristics. |
