Abstract (en)
Gas- or steam-turbine component has a substrate layer (4) under a metal bonding layer (10), a ceramic heat insulation layer (7) and an upper anti-erosion layer (13). The materials making up the bonding layer and anti-erosion layer are the same or of nearly the same composition. Metal bonding layer and anti-erosion layer are an MCrAIX alloy. The bonding layer has 29-31% wt. Nickel, 27-29% wt. Chromium, 7-8% wt. Aluminum, 0.5-0.7% wt. Yttrium and 0.3-0.7% wt. Silicon; the residue is cobalt. The anti-erosion layer consists of 11-13% wt cobalt, 20-22% wt. Chromium, 10.5-11.5% aluminum, 0.3-0.5% Yttrium and 1.5-2.5% Wt. Rhenium; the residue is Nickel. Also claimed is a process to operate a commensurate steam turbine.
