Abstract

A low friction and corrosion resistant valve plug is made by rendering the surface of a metal core porous and then bonding thereto a layer of polytetrafluoroethylene containing fibrous material. If the metal be aluminium, it is made porous by etching with caustic soda. If it be stainless steel, then it may be sprayed or sintered with molten or powdered stainless steel. A dry layer of woven glass fibre is applied to the core which is then dipped in an aqueous dispersion of the resin, subjected to temporary vacuum so that thereafter air pressure forces the resin into the pores and then cured under heat and pressure. According to the Provisional Specification the core is coated with polytetrafluoroethylene or other thermosetting resin and then a preformed polytetrafluoroethylene film, reinforced with glass fibres, is bonded thereto. Before application, the inner surface of the film is roughened, e.g. by grinding to produce a nap of glass fibres.
