FLAME AND/OR PLASMA-SPRAYED POLYMERIC COATINGS.
Abstract
Plasma and flame-sprayed polymeric protective coatings in unpigmented and pigmented forms on stainless steel and titanium substrates have been prepared. Coatings have been obtained from polymers which are insoluble and infusible and which could not be prepared using conventional coatings techniques. Polyaryloxysilane coatings, pigmented with zinc, aluminum, zinc oxide, strontium molybdate and titanium dioxide, were produced by plasma-spraying techniques. Such coatings were generally crack-free (depending on processing conditions) and demonstrated good adhesion to metallic substrates. Plasma-sprayed zinc diphenylphosphinate, pigmented with aluminum, demonstrated good adhesion and high-temperature stability as compared to the unpigmented or zinc oxide-pigmented coatings. Unpigmented and zinc-pigmented polyester coatings were plasma sprayed onto metallic substrates and were found to exhibit good thermal stability in inert environments. Deposits produced by flame-spraying or by plasma-spraying of bisbenzimidazobenzophenanthroline (BBB), parapolyphenylene, and polyperfluorophenylene polymers were poorly melted. (Author)
