Effect of polyethylene glycol on electrodeposition of nano crystalline zinc
Nano crystalline zinc coatings were deposited from acid bromide bath containing polyethylene glycol. The effect of additives and current density on the deposit nature was investigated through Hull cell experiments. The role of polyethylene glycol on cathode current efficiency, rate of build up and nature of deposit at different temperatures were discussed. Micro hardness of zinc deposits was determined. The surface morphology of the zinc deposits was studied by scanning electron microscopy (SEM). The preferred orientation and average size of the zinc electrodeposits were obtained by X-ray diffraction analysis.
