Abstract
The present invention comprises a method for preparing a surface for application of a non-stick coating, the method wherein the surface to be prepared for non-stick coating is prepared by thermally spraying a stainless steel alloy containing at most 6.0% aluminum, and is substantially free of Nickel. The present invention further includes a cooking utensil having a substrate to which an intermediate layer, for receiving the non-stick coating, is prepared by thermally spraying the stainless steel alloy containing at most 6.0% aluminum, and is substantially free of Nickel.
Claims14
A method for preparing a surface for application of a non-stick coating, the method in which the surface to be prepared for non-stick coating is thermally sprayed with a substantially Nickel free stainless steel alloy containing at most 23.5% Chromium and at most 6.0% Aluminum.
A method for preparing a surface for application of a non-stick coating, the method wherein the surface to be prepared for non-stick coating is thermally sprayed with a substantially Nickel free stainless steel alloy having 3.5-6.0% Aluminum (Al) and 14-23.5% Chromium (Cr).
A cooking utensil comprising:
- a substrate and an intermediate layer deposited on the substrate by thermally spraying said substrate with a substantially Nickel free stainless steel alloy containing at most 6.0% Aluminum.
A method for preparing a surface for application of a non-stick coating, the method in which the surface to be prepared for non-stick coating is thermally sprayed with a substantially Nickel free stainless steel alloy.
A cooking utensil comprising:
- a substrate and a layer deposited upon the substrate by thermally spraying said substrate with a substantially nickel free stainless steel alloy.
