Abstract (en)

The housing has an outer layer (5) arranged around an inner layer (4), where the housing is formed as a two-layered structure with the inner layer and the outer layer. The inner layer is made of a more heat resistant material than the outer layer. The more heat resistant material of the inner layer is selected from the group of a nickel-based alloy i.e. alloy 625, the martensitic cast steel or the chromium steel of 9-10 weight percentage. The outer layer is made of the martensitic cast steel, cast steel or the chromium steel of 9-10 weight percentage or 1-2 percentage. An independent claim is also included for a method for manufacturing a two-layered housing for a thermal turbo-machine.
