APPLICATION OF THIN FILMS OF POLYTETRAFLUORO-ETHYLENE COATINGS ON FERROUS MATERIAL
Abstract
Sandblasted and unsandblasted SAE 1020 steel panels were prepared for Teflon coatings. The surface roughness of the sandblasted panels was increased over the original surface roughness, up to a roughness height rating of 270 microinches. All of the steel panels were coated with Teflon and then examined for quality of the coating. Three Teflon coating systems were used. The Teflon adhered well, up to a roughness height rating of 180 microinches, when the coated panels were subjected to a load. The coated panels, when exposed to an accelerated corrosion test, showed corrosion products after 24 hr. Data obtained in this investigation was used to revise NAVORD OD 10362, and is included as an appendix to this report. NAVORD OD 10362 is subject to additional changes as a result of current work.
