The performance effects of pineapple Juice Extract as addition agents on the electroplating of zinc on mild steel in acid chloride solution were experimentally investigated. The experiments were performed under different corrosive media. The zinc electroplating on mild steel was performed using a direct current (DC)-supply at defined operating parameters. The surface of the plated steel was examined using scanning electron microscopy (SEM) for surface morphology. The corrosion resistance of the

... plated surface was determined by potentiostatic polarization method. To evaluate the performance of coatings types in general and oxides, which exist on metal and alloys surface in a special way, were examined by thermal shock test. The quality of the electro-deposition of zinc was good as indicated by the microstructural feature of the plated surface. The electrodeposition process was sensitive to changes in additive concentration and plating time. Variations in the plating parameters produced entirely new and different surface morphology.
