Abstract:
1. Method for production of a corrosion resistant and/or oxidation resistant coating, comprising: depositing by galvanizing at least one metal of the platinum group, or an alloy based on at least one metal of the platinum group, on a surface of a substrate, and thereafter carrying out an aluminizing of the thusly galvanically coated substrate, wherein the galvanic deposition of the or each metal of the platinum group or the corresponding alloy is carried out in an at least two-staged deposition process, whereby in a first stage of the 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 whereby in a second stage of the deposition process the current magnitude applied for the galvanizing is maintained constant at the maximum value.
