Protection layer application, involves applying undercoating with heat insulating layer, and subjecting diffusion layer to abrasive treatment, so that outer structure layer of diffusion layer is removed by abrasive treatment

摘要

The method involves applying a undercoating (3) of MCrAIY base on a base metal layer (1). Undercoating is applied with an alarmed heat insulation layer (2) made of zirconium oxide, where the heat insulation layer is partly stabilized by yttrium oxide. A diffusion layer (4) is subjected to an abrasive treatment, so that an outer structure layer (4.2) of the diffusion layer is removed by the abrasive treatment.
