Class Information
Number: 148/276
Name: Metal treatment > Process of modifying or maintaining internal physical structure (i.e., microstructure) or chemical properties of metal, process of reactive coating of metal and process of chemical-heat removing (e.g., flame-cutting, etc.) or burning of metal > Processes of coating utilizing a reactive composition which reacts with metal substrate or composition therefore > Coating during or after metal oxide formation
Description: Subject matter wherein a reactive composition is applied to a metal substrate and reacts at the surface to form an oxide layer and wherein concurrent with or subsequent to said oxide formation an additional coating process is involved.
