In a nuclear reactor where there are high stresses, temperatures and radiation levels, a number of material problems can occur including corrosion, thermal fatigue cracking, and embrittlement. Material problems are a serious issue in regards to the performance, the advancement, and the safety of nuclear reactors under accident conditions. Fuel cladding materials are of particular significance since cladding is the most important safety barrier, as it contains the majority of radioactive fission products. Nitriding is a method proven to improve many material properties including corrosion and wear resistance. Nitriding works by dissolving or implanting nitrogen into the surface of a material where the nitrogen bonds with the material atoms to form nitrides. The nitriding in these studies is performed by the use of ion bombardment with 40 KeV nitrogen atoms.
