Abstract:
A method for producing a corrosion resistant metal substrate and corrosion resistant metal substrate provided thereby. The method involves forming a plated substrate including a metal substrate provided with a nickel layer or with a nickel and cobalt layer followed by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, which is subsequently subjected to an annealing step in a reducing atmosphere to reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form a diffusion layer which contains nickel and molybdenum, and optionally cobalt.

Claim (Index 1):
A corrosion resistant metal substrate comprising\n a plated substrate comprising a steel or aluminium substrate and a plating layer selected from: i. a nickel or nickel-based layer on the steel or aluminium substrate, or ii. a nickel or nickel-based layer on the steel or aluminium substrate having a cobalt layer on the nickel or nickel-based layer, and a diffusion layer directly on the plating layer; the diffusion layer produced by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, wherein the plated substrate acts as a cathode, wherein the aqueous solution comprises a molybdenum salt and an alkali metal phosphate and wherein the pH of the aqueous solution is adjusted to between 4.0 and 6.5, wherein the plated substrate provided with the molybdenum oxide layer is subjected to an annealing step in a reducing atmosphere to, at least partly and preferably fully, reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form, simultaneously or subsequently, in the annealing step the diffusion layer which contains nickel and molybdenum, and optionally cobalt, wherein the nickel originates from the nickel or nickel-based layer, the cobalt originates from the optional cobalt layer, and the molybdenum originates from the molybdenum oxide layer, wherein the diffusion layer has a thickness of between 10 and 200 nm, wherein the diffusion layer further comprises 5 to 15 wt. % phosphorous.
