In a method for production of a corrosion resistant and/or oxidation resistant coating, at least one metal of the platinum group or an alloy thereof is galvanically deposited onto a surface of a substrate, and thereafter the thusly galvanically coated substrate is aluminized. In a first stage of the galvanic deposition process a current magnitude applied for the galvanizing is increased continuously or step-wise beginning from an initial value up to a maximum value, and in a second stage of the galvanic deposition process the current magnitude applied for the galvanizing is maintained constant at the maximum value. The galvanic deposition of the or each metal of the platinum group or the corresponding alloy may be carried out using an open-celled or open-mesh or porous anode.

Method for producing of a galvanic coating

A component having a corrosion-resistant and/or oxidation-resistant coating is provided that includes at least one platinum-aluminum substrate area is provided, the component having a substrate surface () and a substrate composition based on nickel, with a platinum-aluminum substrate area () formed in the area of the substrate surface of the component by precipitating platinum (Pt) and aluminum (Al) on the substrate surface. The platinum-aluminum substrate area () has a two-phase structure or duplex structure with finely dispersed platinum-aluminum deposits in a nickel-based mixed crystal in an outer zone (), and a single-phase structure made of a nickel-based mixed crystal in an inner zone () located between the substrate surface () of the component and the outer zone ().

Component having a coating

A method and a device for locally removing coatings from components. An absorbent medium supplied with a coating removal liquid is brought into contact with one or more areas of a component from which a coating is to be removed.
