A method for applying a chromium surface treatment to nickel-based air data sensors to improve the corrosion resistance properties of the components while retaining thermal conductivity in order to efficiently transfer internally generated heat to the exterior of the component during anti-icing or deicing procedures is provided. The method for applying a chromium surface treatment to nickel-based air data sensors includes the steps of: (a) ion plating a nickel-based substrate with chromium atoms using a physical vapor deposition process; (b) interdiffusing the chromium and the nickel atoms at the surface region by means of a first thermal treatment carried out in an inert environment; and (c) oxidizing the chromium atoms at the surface region to create a chromium oxide layer during a second thermal treatment performed in an oxygen-containing environment.
