![]() (6063) alloy, copper scraps, sodium chloride ( NaCl), Materials for this research work includes aluminium The aim of this research work was to study the corrosion behaviour of aluminium bronze Result of colonization by marine organisms and severe corrosion attack in sea Replacement for stainless steel components that fail readily in service as a Have shown that aluminum bronze is a fast replacing contemporary steel material for some specific application especially in To those produced abroad and to access the viability of using the materials inĪ typical Nigerian industrial environment. The study is aimed at developing a cost effective aluminium bronze alloy with comparable corrosion resistance With the contemporary method of centrifugal casting used in developedĬountries. Present study investigated the production of aluminium bronze alloy via sand casting method as compared Low magnetic permeability, non-sparking characteristics, aluminum bronzes can Besides their strength, toughness, corrosion resistance in a wide range Hard, body-centered-cubic phase, which enhances properties of castings as wellĪs hot working in wrought alloys. The aluminum content results in higher strength, which is attributable to a Strength and corrosion resistance in a wide range of aggressive media. Therefore, they are used forĪpplications where their resistance to corrosion makes them preferable to otherįeatures often make aluminum bronzes the first choice and sometimes the only logical choice for demanding applications. They show low rates of oxidation at high temperatures and excellentĭioxide and other combustion products. They offer a combination of mechanical andĬhemical properties unmatched by any other alloy series and Is self-healing which means that the alloys can be used under serviceĬonditions where abrasion can be expected. Oxide formed rapidly under normal oxidizing conditions. The aluminiumīronzes in both cast and wrought forms have excellent corrosion resistance ofĪll copper alloys enhanced by the protective film of aluminium Applications of aluminiumīronzes include high pressure flange for sub-sea weapons ejection system,Ĭlutch components for shipboard winch, propellers, landing gear components onĪircraft, wear rings for hydro-turbine, impellers shafts, pumps and valves,Įxchanger parts, non-sparking tools, tube sheets and lots more. Of mechanical properties and corrosion resistance. They areĪvailable in both wrought and cast product forms, and offer good combinations Sometimes intentionally introduced are iron, nickel, manganese, silicon and tinĭepending on the intended application of the aluminium bronze. In selected environments indicated that no corrosion was observed and theĪlloys have a greater tendency to be applicable in marine, alkaline and sulphuric acid environments.Ħ063 Copper Scraps Sand Casting Selective Phase Attack Corrosion Test Īluminium bronzes are copper based alloys withĪluminum as the major alloying element usually in the range 5-11% compositionally in the alloy. Greater corrosion susceptibility of the alloy in HClĮnvironments. IntenseĬhloride attack on the protective film formed on the surface of the aluminium bronze was observed to be responsible for the Minimal corrosion resistance in marine and alkaline media respectively.
