Abstract
The present technology provides a hard-anodized pan that has a steel induction plate and a hybrid coating composition of round ceramic particles. The pan is formed of aluminum with an induction plate affixed. The aluminum is formed into the desired pan shape. The aluminum is sandblasted with beads of a particular size. The sandblasted pan is hard-anodized. The pan is coated with a hybrid coating of round ceramic particles to provide scratch-resistance and a non-stick quality. The pan is coated with a non-stick topcoat.
Claims17
A cooking pan apparatus, wherein at least a portion of the cooking pan apparatus comprises:
- an aluminum base layer, wherein the aluminum base layer is roughened to create a roughened surface and then the roughened surface is hard-anodized to create a hard anodized surface layer;
- an induction plate affixed with the aluminum layer;
- and
- a hybrid coating layer bonded with the hard anodized surface layer opposite the induction plate and comprising spherical inorganic particles, wherein the spherical inorganic particles have a Mohs hardness of 10 and an average circularity of 0.90 to 1.00.
A method to construct a cooking pan apparatus, comprising:
- affixing an aluminum base layer to an induction plate;
- forming the aluminum base layer and the induction plate into a desired shape;
- roughening a surface of the aluminum base layer to create a roughened aluminum surface;
- anodizing the roughened aluminum surface of the aluminum base layer to create a hard anodized surface layer;
- and
- applying a hybrid coating layer onto the hard anodized surface layer opposite the induction plate, the hybrid coating layer comprising spherical inorganic particles, wherein the spherical inorganic particles have a Mohs hardness of 10 and an average circularity of 0.90 to 1.00.
