高性能铝青铜合金的制备及其腐蚀与磨损性能研究进展OA

Aluminum bronze alloys are a type of bronze alloy formed by mainly adding aluminum to copper,along with other alloying elements such as nickel and iron.Aluminum bronze alloys feature excellent mechanical properties,wear resistance and corrosion resistance,and are widely used as gears,valves and propellers.With rapid advancement of industrial technology,increasingly stringent requirements are being imposed on various properties of aluminum bronze.For traditional as-cast aluminum bronze,the presence of casting defects combined with complex multiphase structure makes it susceptible to failure under specific service conditions.The composition,microstructure,and properties of the alloy should be systematically optimized and improved in a targeted manner to meet specific requirements of service conditions.This paper investigated intrinsic relationship among preparation process,microstructural characteristics,as well as mechanical,corrosion,and wear properties of aluminum bronze alloys.It provided a comprehensive review of recent advancements in the development of high-performance aluminum bronzes through alloying,heat treatment,additive manufacturing,surface modification,and other processes.Corrosion resistance and friction-wear resistance of aluminum bronze under various technological conditions were systematically summarized and analyzed before potential future research directions were outlined.
