Patent number: 6602368Abstract: A method of coating core having a metal surface with a uniform thickness, smooth, thin layer of fluorinated polymer calls for inserting the core into a sleeve of the polymer. The sleeve has an inner diameter slightly smaller than the outer diameter of the core so that the sleeve stretches to form a skin-tight fit over the core upon insertion. The assembly of sleeve and core is then subjected, in sequence, to aging under vacuum at a temperature below the softening point of the polymer prior, heating to a temperature above the softening point, and cooling below the softening point to thermally bond the fluorinated polymer to the metal surface. A firm bond is achieved without additional adhesive components or etching of the surface. A fuser roll for suitable for electrophotographic copy machine service can be prepared by this method without the need for a separate, post-bonding burnishing step to smooth the exposed surface of the fluorinated polymer layer.Type: GrantFiled: February 21, 2001Date of Patent: August 5, 2003Assignee: Saint-Gobain Performance Plastics CorporationInventor: Martin Geiger
