Abstract

A turbomachine component is provided having at least two sub-components that are separated by a parting joint and each have a sealing surface at the parting joint, at least one of the two sealing surfaces being convex in order to form a linear contact of the two sealing surfaces. At least one of the sealing surfaces has a coating on it which includes a hard material, is a maximum of 30 μm thick and is applied using a vapour deposition method, or a coating which includes a chrome-containing alloy, is a maximum of 30 μm thick and is applied by a vapour deposition method, or is a maximum of 300 μm thick and applied using a thermal spraying method.
