Patent ID: 8047775

Claim:
A layer system for a component, comprising: a substrate; a metallic bonding layer, an erosion-resistant layer; wherein the metallic bonding layer is selected from the group consisting of: 9%-31% nickel (in wt %), 27%-29% chromium (in wt %), 7%-8% aluminum (in wt %), 0.5%-0.7% yttrium (in wt %), 0.3%-0.7% silicon (in wt %), remainder cobalt, 11%-13% cobalt (in wt %), 20%-22% chromium (in wt %), 10.5%-11.5% aluminum (in wt %), 0.3%-0.5% yttrium (in wt %), 1.5%-2.5% rhenium (in wt %), remainder nickel, 24%-26% cobalt (in wt %), 16%-18% chromium (in wt %), 9.5%-11% aluminum (in wt %), 0.3%-0.5% yttrium (in wt %), 1.0%-1.8% rhenium (in wt %), remainder nickel, 11.5%-20% chromium (in wt %), 0.3%-1.5% silicon (in wt %), 0%-1% aluminum (in wt %), 0%-4% yttrium (in wt %), remainder iron, and 12.5%-14% chromium (in wt %), 0.5%-1.0% silicon (in wt %), 0.1%-0.5% aluminum (in wt %), 0%-4% yttrium (in wt %), remainder iron, wherein the bonding layer and the erosion-resistant layer have a similar composition; a thermal barrier coating on the metallic bonding layer; and an outer metallic erosion-resistant layer on the thermal barrier coating.
