Corrosion Behaviour of Annealed Cn_(x)/Tin_(y) Multilayers

摘要

The corrosion behaviour of annealed CNx/TiNy multilayers have been investigated using potentiodynamic test in a 0.5MH2SO4 solution. The coating has been deposited on W6Mo5Cr4V2 steel by reactive magnetron sputtering and then annealed at different temperature. The annealed multilayers showed superior corrosion resistance as compared to the as-deposited coating. The corrosion model of annealed CNx/TiNy multilayers has been set up.
