Class Information
Number: 148/242
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 > Molten bath or molten surface utilized during reaction
Description: Subject matter wherein the coating material is a solid at ambient temperature but is in a partially or fully melted state or wherein the normally solid metal substrate is in a partially melted condition.
