Title
(EN) POWDER METAL AND/OR REFRACTORY COATED FERROUS METALS
(FR) POUDRE METALLIQUE ET/OU METAUX REFRACTAIRES ENDUITS
Abstract
(EN)
Coatings of a powdered protective metallic material or refractory material and mixtures thereof are formed on a ferrous metal strip as a wet film dispersion in a resin binder composition of a synthetic organic resin and a volatile organic solvent compatible with said resin, and the coated strip is heated to effect curing saidresin binder and forming a flexible non-tacky dry film. The metal strip having the cured dry film containing powdered protective metallic material can be subjected to varying heat treatments to provide a wide range of protective coatings having improved surface properties, including iron-protective metal diffusion alloy coatings, such as iron-aluminum diffusion alloy coatings having a surface concentration of aluminum between about 8 and about 10 wt. percent aluminum, which have improved high temperature oxidation resistance after being severely strained during fabrication at room temperture.
(FR)
Des revêtements de matériau métallique protecteur pulvérisé ou de matériau réfractaire et de mélanges de ceux-ci sont formés sur une bande de métal ferreux en tant que dispersion de film humide dans une composition de charge formée d'une résine organique synthétique et d'un solvant organique volatile compatible avec ladite résine; la bande enduite est chauffée pour effectuer la polymérisation de ladite charge et former un film sec flexible et non poisseux. La bande métallique comportant le film sec polymérisé contenant le matériau métallique protecteur pulvérisé peut être soumise à divers traitements thermiques afin d'offrir un grand choix de revêtements protecteurs dotés de propriétés de surface améliorées, y compris des revêtements d'alliage par diffusion de métal protégeant le fer, comme des revêtements d'alliage par diffusion de fer et d'aluminium possédant une concentration superficielle d'aluminium située entre environ 8 et environ 10% en poids d'aluminium qui présentent une résistance à l'oxydation à haute température améliorée après avoir subi d'importantes déformations pendant la fabrication à température ambiante.
