Abstract

Zinc electrodeposition from mixed ammonium chloride/potassium chloride bath was carried out and the influence of plating time on the rest potential, white rust and red rust was studied. The zinc plated mild steel specimens were divided into four categories: non-chromated, yellow-chromated, greenish-grey chromated and black-chromated zinc plated mild steel specimens. There is no effect of plating time on the rest potential. The time taken for white rust and red rust increased with increase in plating time. Black-chromated zinc plated mild steel specimens have maximum corrosion resistance. The abrasion resistance of yellow-chromated zinc plated mild steel specimens was very poor. The appearance and adhesion of the deposits were good.
