Experimental investigations on corrosion behavior and antibacterial property of nickel-aluminum bronze fabricated through wire-arc additive manufacturing (WAAM)
CORROSION SCIENCE(2023)
摘要
This paper discussed the differences in corrosion resistance and antimicrobial properties between nickel-aluminum bronze (NAB) fabricated by WAAM and cast. Compared with castings, the grain size of WAAM-NAB was smaller, and the precipitation of the kappa phase was limited. The corrosion of WAAM-NAB occurred in the residual beta phase with a suppression of selective phase corrosion, so its corrosion resistance was improved. The Cu ions of the WAAM-NAB were released more rapidly to achieve a more effective sterilization. The mi-crobial corrosion resistance of WAAM-NAB was better than that of cast alloys.
