摘要：The mechanical properties and corrosion behaviour in 3.5 wt.% NaCl solution of as-cast nickel-aluminium bronze (NAB) alloys with four Ni contents were investigated. The increase in Ni content leads to more precipitated kappa phases, therefore improving the yield strength and hardness of the NAB alloys. Ni addition was found to significantly suppress the formation of corrodible beta' phase and increase the Ni concentration in alpha solid solution. The electrochemical impedance spectroscopic and static immersion tests showed that the increase in Ni content (4.5-10 wt.%) improved the corrosion resistance of the NAB alloys in 3.5 wt.% NaCl solution.
