A method of producing a ceramic layer on a surface formed of a Ni-based alloy and a ceramic layer article

摘要

A method for producing a ceramic layer (18) on a surface formed from a Ni-based alloy (17), comprising the following steps: producing a ceramic layer (18) containing ZrO2 as a main component on the surface; Production of a gas phase with a temperature in the range from 400 to 900 ° C, in which in a carrier gas formed from an inert gas with an addition of 0.5 to 10 wt.% HCl a molten salt (8) with the components alkali chloride Alkali sulfate-ZnCl2 formed vapor is contained; and bringing the ceramic layer (18) into contact with the gas phase for a period of time which is sufficient for an intermediate layer (19) with a thickness of at least 0.1 μm to form between the ceramic layer (18) and the surface.
