Method for preparing a high temperature polymer coating

摘要

A method for coating a substrate includes impacting a substrate with a plurality of particles such that the particles adhere to the substrate, bonding the particles to the substrate to form an overlayer, and crosslinking the particles in the overlayer to coat the substrate with a crosslinked polymer coating. The particles comprise a polyphenyl polymer. An article includes a substrate and a crosslinked polymer coating bonded to the substrate. The crosslinked polymer coating is a product of crosslinking polyphenylene sulfide, polyphenylsulfone, self-reinforced polyphenylene, or a combination thereof on a surface of the substrate.

1. A method for coating a substrate, the method comprising:
impacting a substrate with a plurality of particles such that the particles adhere to the substrate, the particles comprising a polyphenyl polymer; bonding the particles to the substrate to form an overlayer; and crosslinking the particles in the overlayer to coat the substrate with a crosslinked polymer coating; wherein the particles further comprise a crosslinker, the crosslinker comprising one or more of the following: sulfur; a peroxy compound; a metal peroxide; or a metal oxide; wherein the metal oxide comprises one or more of the following: zinc oxide; magnesium oxide; or titanium dioxide.
