The Effect of Alloy Elements Ni and Mn Addition on Wear and Cavitations Corrosion Properties of Aluminum Bronze Mohsen Moradlou m moradlou@ma iut ac ir August 11 2009 Department of Materials Engineering Isfahan University of Technology 84156 83111 Isfahan Iran Degree M Sc Language Farsi Dr Rahmatollah Emadi Assist Prof Supervisor E mail remadi@cc iut ac irAbstractAluminum bronzes are copper base alloys with high strength that aluminum existence in this alloyesstrengthens them By increasing the aluminum percentage alloys strength increase too Alloy elements suchas Ni Mn Fe and Si are added to produce the different types of this alloy with various properties of strength ductility corrosion resistance and magnetic penetrability These alloys have suitable wear resistance castability in different casting methods and good weld ability These alloys show high corrosion resistance in sea chloride and weak acid environments Application of these alloys is much extended and includes propellers valves wear rings In this study different percentage of alloy elements Ni and Mn were added similarly of0 15 To evaluate the effects of these additions mechanical and corrosion properties were investigated andthe best percentage was determined Micro structure of casted alloys was studied by a scanning electronmicroscope SEM and EDS analysis was carried out to phases identify To corrosion properties evaluation polarization test immersion test and cavitation erosion test were done Hardness and pin on disc wear testswere carried out to investigate the mechanical and tribological properties The results showed the alloys with10 Ni and Mn have best corrosion resistance wear resistance and mechanical properties Addition of Niand Mn above 10 causes brittle phases that penetrate in transgranular and border grains and makes themweak Cavitation corrosion test results showed that by alloys elements above 4 cavitation resistance in 6 hrperiods is very good Keywords aluminum Bronze Alloying Heat Treatment Cavitation Corrosion Sea applications
