Pack diffusion on an interlayer

摘要

Method for modifying a substrate with a diffusion layer comprises forming the diffusion layer made from a layer of nickel, nickel-tungsten, nickel-molybdenum or nickel-cobalt alloy as intermediate layer by subsequently applying an outer layer made from aluminum, chromium, silicon and/or titanium using a packing method or by chemical gas phase deposition in a simultaneous thermal treatment. Independent claims are also included for the following: (1) Diffusion-coated substrate produced by the above method; (2) Workpiece with the diffusion-coated substrate; and (3) Diffusion layer for arranging on a substrate.
