Claims
- 1. 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.
- 2. The method of claim 1 wherein the substantially Nickel free stainless steel alloy contains from 14-23.5% chromium by weight.
- 3. The method of claim 1 wherein the substantially Nickel free stainless steel alloy contains from 3.5-6.0% by weight of aluminum.
- 4. 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).
- 5. The method of claim 4 wherein the formulation for the substantially Nickel free stainless steel alloy further comprises: 0.45% (maximum) Manganese (Mn), 0.65% (maximum) Silicon (Si), 0.055% (maximum) Carbon (C), and 70.35-74.35 parts iron (Fe).
- 6. 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.
- 7. The cooking utensil of claim 6 wherein the substantially Nickel free stainless steel alloy contains from 14-23.5% chromium by weight.
- 8. The cooking utensil of claim 6 wherein the substantially Nickel free stainless steel alloy contains from 3.5-6.0% by weight of aluminum.
- 9. The cooking utensil of claim 6 wherein the formulation for the substantially Nickel free stainless steel alloy further comprises: 0.45% (maximum) Manganese (Mn), 0.65% (maximum) Silicon (Si), 0.055% (maximum) Carbon (C), and 70.35-74.35 parts iron (Fe).
- 10. 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.
- 11. The method of claim 10 wherein the substantially Nickel free stainless steel alloy contains at most 23.5% Chromium.
- 12. The method of claim 10 wherein the substantially Nickel free stainless steel alloy contains at most 6.0% aluminum.
- 13. 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.
- 14. The cooking utensil of claim 13 wherein the layer deposited upon the substrate by thermally spraying said substrate with a substantially Nickel free stainless steel alloy contains at most 23.5% Chromium.
