Protective coatings for metals

摘要

Metal products having improved properties and processes for preparing the metal products are provided. In an embodiment, the present disclosure provides for a metal product comprising a metal surface, an oxide layer and a glass layer. The glass layer is provided by coating a stable aqueous silicate or borosilicate solution onto the metal surface and curing the aqueous solution to produce a glass layer. The metal products have surface characteristics that outperform current anodized metal surfaces.
