Electrodeposition of Zinc from Acid Based Solutions: A Review and Experimental Study

C.A. Loto

Abstract

The need to prevent corrosion, toxicity and to enhance the aesthetic value of steel components in automotive, construction, electrical, appliances, recreational and materials handling industries and in our daily lives, has led to an enlarged interest in the field of electrodeposition of zinc on steel substrates. The toxicity and stringent regulation against water pollution and hence costly effluent disposal of cyanide based baths has led to the increased interest and accelerated growth of acid zinc based baths in the past few years. This study reviews the recent progress and development, bath solution and composition, effect and type of addition agents and practical aspects of acid based solutions. The corrosion resistance of the electrodeposited zinc coatings is also examined. The effectiveness of the cassava and sugar cane juices separately and the synergistic effect of the two juices combined is experimentally reported.
