ABSTRACT:
The present invention relates to the use of a pre-coating process, which utilizes metallic plating as a surface pre-treatment for a ferrous-alloy precursor prior to applying a corrosion-inhibiting coating to improve the overall corrosion protection of the pre-treated and pre-coated component. Preferably the ferrous-alloy precursor is a heat-treatable, precipitation-hardenable stainless-steel material and the pre-treatment is a cadmium or a zinc-nickel alloy plating without a subsequent chromate or phosphate seal finish.
