Anticorrosion behaviour and tribology study of Zn-CeO2-SnO2 coating produced

摘要：

　　The application of good design principles and process in electrodeposition can eliminate many engineering problems associated with corrosion and micromechanical failure in defense application.Hence, there is need for surface modification of materials for enhanced life span.Admixed Zn-CeO2-SnO2 sulphate composite bath was electrolytically prepared and successfully deposited on mild steel substrate by zinc dual anode deposition processes at different particle concentration and constant time.The effect of particle concentration on structural property, surface topography and electrochemical progression of Zn-CeO2-SnO2 alloy coating series on mild steel were analytically evaluated.The wear resistance of the Zn-CeO2-SnO2 materials obtained was determined via sliding reciprocating rig.The structural integrity was examined using scanning electron microscope equipped with EDS, dura scan micro-hardness tester and 3μ metrohmPotentiostat/galvanostat.The results obtained showed that SnO2 nanoparticles produced excellent surface morphology, improved hardness property, low wear rate and improved corrosion resistance of Zn-CeO2-SnO2 composite alloy.
