| Abstract: | In this paper, chemical compositions of new cast Ni-Cu alloy are designed. Several kinds of methods of corrosion test are applied to investigate the uniform corrosion,intergranular corrosion and pitting corrosion behaviour of the alloy. Experimental results show that, cast Ni-Cu alloy prossesses good uniform corrosion and local corrosion resistance. In addition,this alloy also possesses better synthetical properties and casting behayiours. |
