COATING FOR COOKING VESSEL

摘要

A method of preparing and coating metal cookware having an interior cooking surface (80) and for the application of a lubricative coating is disclosed. The method includes mechanically spraying the interior cooking surface (80) with an aluminum oxide material to produce a roughened surface (80) and applying by thermal spraying a metallic abrasion resistant layer (11) of substantially pure titanium. Titanium oxide and titanium nitride are also formed. Also disclosed is a cooking utensil having a substrate (80) and an intermediate layer (11) deposited on the substrate by thermally spraying the substrate with a mechanically durable material (11), said mechanically durable material being selected from the group consisting of chemically pure titanium, titanium-aluminum, and titanium 6-4.
