METAL SURFACES COMPRISING A THIN GLASS- OR CERAMIC-TYPE PROTECTIVE LAYER HAVING HIGH CHEMICAL RESISTANCE AND IMPROVED NON-STICK PROPERTIES

摘要

The invention relates to items comprising a metal surface that is provided with a glass-, glass ceramic- or ceramic-type protective layer, characterized in that the protective layer has a base layer comprising a matrix made of an alkali and/or earth alkali silicate and an alkali metal- and alkaline earth metal-free cover layer comprising a matrix made of an oxidic silicon compound, and to a method for producing said items. The items comprising the protective layer exhibit high chemical resistance and improved non-stick properties. They are characterized in particular by high dishwashing resistance.
