ABSTRACT:
A method for regenerating an extrusion die for ceramic honeycomb structural bodies. The extrusion die includes a base metal and a titanium-based hard coating of an abrasion-resistant material which is formed on a surface of the base metal. The extrusion die is immersed in a solution of nitric acid when it has worn, so as to remove a residue of the hard coating from the surface of the base metal. Subsequently, a titanium-based fresh hard coating is formed on the surface of the base metal, and a pattern adjustment of the die is then performed wherein the surface of the fresh hard coating is locally ground so that the sliding resistance of the raw ceramic material becomes substantially uniform over the entire region of the die.
