摘要
The invention relates to a method for adjusting the number of phases of a PtA1-layer of a component of an aircraft engine when producing said type of layer during production or reconditioning of said type of component of an aircraft engine. The following steps are carried out in order to produce a single-phase PtA1-layer on a gas turbine component: a Pt-layer is placed on the gas turbine component, the thickness thereof being less than 4 µm; homogenisation such that the Pt in the base material of the gas turbine component is diffused; and aluminised and controlled such that a A1-content, that is smaller than or equal to 23 % in weight, is adjusted; and the following steps are carried out in order to produce a two-phase PtA1-layer on the gas turbine component; a Pt-layer is placed on the gas turbine component, the thickness thereof being in the region of 5 µm - 8 µm; homogenisation such that the Pt in the base material of the gas turbine component is diffused; and aluminised in order to produce the PtA1-layer. The invention also relates to a method for producing a single-phase PtA1-layer on a gas turbine component.
