UNS G10150 steel was electrodeposited with Zn-30Al-7%Ti, in the presence ofudsolanum tuberosum, under sulphate condition, via dual anode route. The microstructuresudof the deposited layers were examined using scanning electron microscopy (SEM),udatomic force microscope and X-ray diffractometry (XRD). The microhardnessudproperties and wear characteristics were performed using a diamond basedudmicrohardness tester and a CERT reciprocating sliding tester. The microstructureudrevealed a massive structural transformation with hexagonal dendritic and whisker-likeudstructure for the Zn-30Al-7%Ti coating. There was a significant rise in surface microudhardness values of the co-deposited layers, due to the presence of hard phase TiO2udparticles, and solanum precipitation. The surface strengthening effect induced byudsolanum, and Al/TiO2 addition, with the presence of Zn2Al3Ti2, could be responsible forudlow plastic deformation and improved hardness of the coating. It is established that theudelectrodeposition route via dual anode of Zn-Al-Ti with adsorbed fluid on UNS G10150udsteel can be used to improve the surface hardness values, aesthetic properties and wearudresistance.
