Stain-Resistant Cooking Surface and Cookware Item or Electrical Household Appliance Comprising such a Cooking Surface

This invention describes a special, hard coating for cooking surfaces, like those on pans or electric appliances, to make them stain-resistant. It's made by depositing a layer of metal nitrides, specifically a mix of niobium and/or zirconium with aluminum, onto the cooking surface. The key is that at least 20% of the metal in this coating is aluminum, making it a unique blend for durability.

Why it matters: Since 2012, advancements in reactive sputtering and materials science have refined the deposition of complex nitride coatings, potentially making this durable, stain-resistant surface more cost-effective and scalable for consumer products.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedReactive sputtering, vacuum deposition, nitridation
