PROCEDE AMELIORE DE PRE-TRAITEMENT DE SURFACE POUR DES ALLIAGES FERREUX EN ACIER INOXYDABLE PRE-ENDUITS, APTES AU TRAITEMENT THERMIQUE ET AU DURCISSEMENT PAR PRECIPITATION AINSI QUE COMPOSANTS ENDUITS DE CETTE MANIERE

摘要

Coating an aircraft structural component made of ferrous alloy comprises subjecting the component to a veil pretreatment (term not defined), coating the component with a hardenable organic coating material, and simultaneously heat-treating the component and hardening the coating. Independent claims are also included for: (1) improving the anticorrosion protection of a ferrous alloy substrate by applying a veil pretreatment to the substrate without subsequent chromate sealing and applying a hardenable organic coating material having a nonvolatile component that can be hardened at a predetermined heat treatment temperature of the ferrous alloy; (2) aircraft structural component made of ferrous alloy comprising a ferrous alloy precursor having a predetermined heat treatment temperature; a veil as a preteatment without subsequent chromate sealing; and a hardenable organic coating consisting of a material having a nonvolatile component that can be hardened at the predetermined heat treatment temperature of the ferrous alloy, where the precursor and the coating are heat treated simultaneously.
