Abstract
(EN)
 The purpose of the present invention is to provide a method for manufacturing a coated mold for die casting, the mold having exceptional seizure resistance and erosion resistance with respect to molten metal. This method for manufacturing a coated mold for die casting has a step for coating the surface of the base material of a die casting mold with a first hard coating film by an arc ion plating process, a step for carrying out a treatment for leveling the surface of the first hard coating film, and a step for coating the leveled first hard coating film with a second hard coating film by an arc ion plating process.

 La présente invention concerne un procédé de fabrication d'un moule revêtu pour moulage sous pression, ledit moule étant exceptionnel en termes de résistance au grippage et de résistance à l'érosion par rapport au métal fondu. Ce procédé de fabrication d'un moule revêtu pour moulage sous pression comporte les étapes suivantes : une étape de revêtement de la surface du matériau de base d'un moule moulé sous pression avec un premier film de revêtement dur, par un procédé de placage ionique à l'arc; une étape de mise en œuvre d'un traitement permettant de niveler la surface du premier film de revêtement dur; et une étape de revêtement du premier film de revêtement dur nivelé avec un second film de revêtement dur, par un procédé de placage ionique à l'arc.
