| 20100183811 | METHOD FOR ADJUSTING THE NUMBER OF PHASES OF A PTAl-LAYER OF A GAS TURBINE COMPONENT AND METHOD FOR PRODUCING A SINGLE-PHASE PTAl-LAYER ON A GAS TURBINE COMPONENT - A method for adjusting the number of phases of a PtAl layer of a component of an aircraft engine is disclosed. In an embodiment, the following steps produce a single-phase PtAl layer on the gas turbine component: application of a Pt layer to the gas turbine component, the thickness thereof being less than 4 μm; homogenization such that the Pt in the base material of the gas turbine component is diffused; and aluminization and control such that an Al content that is less than or equal to 23% by weight is adjusted; and the following steps produce a two-phase PtAl layer: application of a Pt layer to the gas turbine component, the thickness thereof being in the range of 5 μm to 8 μm; homogenization such that the Pt in the base material of the gas turbine component is diffused; and aluminization in order to produce the PtAl layer. | 07-22-2010 |
