Abstract
Disclosed is a process for producing an alloyed, in particular multiple-alloyed aluminide or chromide layer on a component by alitizing or chromizing. First a green compact layer (9) consisting of a binder (5) and metal particles (7) is deposited on the component (1) to be coated and then alitizing or chromizing is carried out, binder and metal particles being deposited on the component separately from one another, first the binder and then the metal particles. A turbine component produced by this process is also disclosed.
Claims20
A process for producing at least one alloyed aluminide and/or chromide layer on a component by alitizing and/or chromizing, wherein the process comprises depositing a green compact layer of a binder and metal particles on the component to be coated and thereafter carrying out alitizing and/or chromizing, the binder and the metal particles being deposited on the component separately from one another by first applying the binder to form a binder layer, and then depositing the metal particles on or in the binder layer.
A turbine component comprising at least one cavity, wherein at least one alloyed aluminide and/or chromide layer is formed on a surface of the turbine component in the cavity.
