Abstract
A method for producing a ceramic layer on a surface formed from a Ni base alloy, includes the following steps: producing on the surface a ceramic layer containing ZrOas a main constituent; producing a gas phase having a temperature in the range from 400 to 900° C., in which a vapor formed from a salt melt with the components alkali chloride, alkali sulphate and ZnClis contained in a carrier gas formed from an inert gas with an addition from 0.5 to 10% by weight HCl; and bringing the ceramic layer into contact with the gas phase for a period of time that is sufficient for an intermediate layer having a thickness of at least 0.1 μm to form between the ceramic layer and the surface.
