Abstract
A method of integrally bonding self-lubricating material to an external surface of a substratum to form a self-lubricating surface thereon comprising the steps of: A. forming the substratum to provide an external surface thereon of desired configuration; B. applying a layer of self-lubricating material onto the surface; C. applying a plurality of filaments on the layer of self-lubricating material to form an overlayment thereon to exert a bonding pressure sufficient to cause the layer of self-lubricating material to conform and bond to the configured external surface; D. applying a hardenable liquid resin prior to, simultaneously with, or subsequent to the application of the self-lubricating material and filaments to coat the material and filaments and fill any interstices that exist; E. hardening the resin; and F. removing all or part of the overlayment after the resin has hardened to expose the layer of self-lubricating material or portions thereof on the external surface.
