A Novel Effect of Solanum Tuberosum/Zn-30Al-7Ti Sulphate Modified Coating on UNS G10150 Mild Steel Via Dual-anode Electrodeposition Route

UNS G10150 steel was electrodeposited with Zn-30Al-7%Ti, in the presence of solanum tuberosum, under sulphate condition, via dual anode route.The microstructures of the deposited layers were examined using scanning electron microscopy (SEM), atomic force microscope and X-ray diffractometry (XRD).The microhardness properties and wear characteristics were performed using a diamond based microhardness tester and a CERT reciprocating sliding tester.The microstructure revealed a massive structural transformation with hexagonal dendritic and whisker-like structure for the Zn-30Al-7%Ti coating.There was a significant rise in surface micro hardness values of the co-deposited layers, due to the presence of hard phase TiO 2 particles, and solanum precipitation.The surface strengthening effect induced by solanum, and Al/TiO 2 addition, with the presence of Zn 2 Al 3 Ti 2 , could be responsible for low plastic deformation and improved hardness of the coating.It is established that the electrodeposition route via dual anode of Zn-Al-Ti with adsorbed fluid on UNS G10150 steel can be used to improve the surface hardness values, aesthetic properties and wear resistance.
