METHOD FOR CERAMIC COATING ON METALS

摘要

The invention is a ceramic-coated heat-resistant metal article and process for preparing the article. An aluminum phosphate coating is applied to the metal substrate and a ceramic coating is applied over the aluminum phosphate coated metal substrate. The aluminum phosphate coating can be applied chemically or electrolytically. The ceramic coating can be applied by known methods such as dipping, spraying, chemical vapor deposition, sputtering and flame coating.
