摘要
Abstract
Nickel-aluminum bronze alloys are widely used in various fields such as petroleum and natural gas pump systems,aerospace industry,and ship applications due to their excellent ductility,strength,fracture toughness,and corrosion resistance.Traditional cast-ing processes for nickel-aluminum bronze result in complex phase compositions,making them susceptible to severe corrosion failure in harsh service environments.In recent years,additive manufacturing technology has rapidly advanced in the processing of copper alloys.Leveraging the rapid non-equilibrium solidification characteristics,this technology enables microstructure control to enhance the me-chanical properties of copper alloys.Additionally,it holds the potential to improve their corrosion resistance in demanding service con-ditions.This paper presents examples of nickel-aluminum bronze alloys prepared by different additive manufacturing technologies.A comprehensive exploration is conducted focusing on their microstructure,mechanical properties and corrosion behavior.Furthermore,a comparative analysis is performed on various processing parameters and heat treatment processes,examining their correlation with the microstructure of nickel-aluminum bronze and the resulting impact on corrosion behavior.By establishing the intrinsic relationship be-tween additive manufacturing processes,microstructure characteristics and corrosion resistance of nickel-aluminum bronze,this paper provides a thorough theoretical foundation and practical guidance for the design optimization and application of high-performance addi-tively manufactured nickel-aluminum bronze.关键词
