Abstract:
A process for surface treating iron-based alloy includes providing a substrate made of iron-based alloy. A chromium layer is then formed on the substrate by vacuum sputtering. A silicon oxide layer, an alumina layer, and a boron nitride layer are formed in that order by vacuum evaporation.
