A coating (3) is deposited onto a surface (2) of a component (1) in a light water reactor, said coating (3) being in contact with water, water steam or a combination thereof during use and having as its task to protect the surface (2) against oxidation, hydration, corrosion and wear. The coating (3) is comprised by two or more layers (4), adjacent layers (4) having different structure, composition or being comprised by different materials. Examples of suitable materials for the layers (4) are titanium (Ti), titanium nitride (TiN), titanium dioxide (TiO2), titanium carbon nitride (TiCN), titanium aluminium nitride (TiAIN), zirkonium dioxide (ZrO2), zirkonium nitride (ZrN) and diamond-like coal (DLC) and mixtures thereof. |
