Definitions
- the invention relates to the refinement of surfaces by remelting and build-up welding and a component.
- Step 1 is only an embodiment of the invention ⁇ It is proposed a method which comprises two steps. Step 1:
- Step 2 By remelting a surface of a substrate is ⁇ works. By remelting, in particular by means of a laser beam, it is possible to generate long grains along the remelted trace so that grain boundaries on the surface are removed. Step 2 :
- epitaxial deposition welding in particular by means of laser, can be an oxidation resistant layer, in particular ⁇ sondere of NiCoCrAlY, order-weld to the remelted zone, so that this particular epitaxially grows without grain boundaries or korngrenzenarm on the substrate (identi ⁇ specific crystallographic orientation as the base material) ,
- This procedure improves the oxidation resistance on the surfaces of polycrystalline solidified components of nickel-base superalloys, in particular because epitaxy provides fewer grain boundaries for oxidation damage and additionally generates additional oxidation protection by coating.
