There is disclosed a method of depositing a nanocomposite coating of stainless
steel and a metallic carbide or metallic nitride, e.g. chromium carbide or chromium
nitride, onto a stainless steel substrate 10, including the steps of (a)
providing the stainless steel substrate 10; (b) depositing stainless steel
on the substrate 10; (c) depositing chromium carbide or chromium nitride
on the substrate 10; and allowing a nanocomposite coating 14 of the
stainless steel and chromium carbide or chromium nitride to form on the substrate
10.
