It is researched the preparation of ceramic layer on the surface of M5 zirconium alloy by high-frequency induction oxidation process in active flow oxygen medium and in dry air.

： The out- of- pile and in- pile corrosion,mechanical properties,microstructure,hydrogen absorption,creep and growth resistances of M5 alloy using as PWR fuel rod cladding materials developed by FRAMATOME in France has been summarized with reference to the literatures.

M5 alloy was a new zirconium alloy used in high burn up assembly such as fuel cladding,end plug,guide tube and grid spring and so on.

Based on the analysis of welding properties of zirconium and zirconium alloys,and through the welding test and research,the zirconium and zirconium alloy piping welding process has been obtained and summarized,and the welding technical specification was also stipulated.
