The process for hot-shaping through massive forming such as forging or rolling a workpiece or raw material of metal or intermetallic compound at a temperature of above 1000[deg] C, comprises partially coating a surface of the workpiece or raw material with a coating agent that comprises an oxide phase and an additive, an adhesive or a binder, and allowing the coating to solidify after which a preheating step is carried out with through-heating of the coated workpiece or raw material to deforming temperature and then transfers the coated workpiece or raw material to a shaping device.

A temperature of the surface of the workpiece or raw material to be coated is above 200[deg] C. The coating of the workpiece or raw material takes place by immersing into the coating agent and spraying with the coating agent. A solidified layer thickness of the coating is 0.3-3 mm. An independent claim is included for a coating agent. |
