Corrosion-resistant and stain-resistant component and method for manufacturing same
View Patent ↗A multi-layer corrosion protection system and a method for applying the multi-layer corrosion protection system. The system comprises a corrosion-resistant layer plated onto a metallic substrate. The corrosion-resistant layer may be deposited using an autocatalytic (electroless) process. The corrosion-resistant layer may comprise phosphorous. The system comprises a stain-resistant layer deposited over the corrosion-resistant layer. The stain-resistant layer may be deposited using an autocatalytic (electroless) process. The stain-resistant layer may comprise nickel. The system may also comprise an inner layer plated onto the metallic substrate to prepare the metallic substrate for the application of the corrosion-resistant layer. The inner layer may comprise nickel and may be deposited using an autocatalytic (electroless) process.
1. An apparatus, comprising:
a metallic substrate;
an electroless nickel alloy layer disposed over the metallic substrate, wherein the electroless nickel alloy layer comprises phosphorous;
an outer electrolytic nickel layer disposed over the electroless nickel alloy layer; and
an inner electrolytic nickel layer disposed over the metallic substrate, wherein the electroless nickel alloy layer is disposed over the inner electrolytic nickel layer.
2. The apparatus as recited in claim 1 , comprising a polymeric coating layer disposed over the outer electrolytic nickel layer.
3. The apparatus as recited in claim 1 , wherein the outer electrolytic nickel layer consists essentially of nickel.
4. An apparatus, comprising:
a metallic substrate;
a first Wood's nickel strike layer disposed over the metallic substrate;
an electroless nickel-containing layer disposed over the first Wood's nickel strike layer;
a second Wood's nickel strike layer disposed over the electroless nickel layer; and
a polymeric layer disposed over the second Wood's nickel strike layer.
