In this study, nano-ZnO particles were deposited on mild steel sheets from an acidic zinc bath. These particles were synthesized by using an auto combustion technique. The effect of concentration of nano- ZnO particles on the corrosion behavior of depositions was investigated. The results of salt spray tests and electrochemical measurements showed that corrosion resistance is improved by additi...

This work reports the feasibility of applying emulsion pertraction technology (EPT) aiming at zinc recovery and waste minimization in the zinc electroplating processes that include Cr (III) passivation. The assessment consists of firstly the lifetime extension of the passivation baths by selective removal of the tramp ions zinc and iron, and secondly, the recovery of zinc for further reuse. Spe...

Abstract Today, lead, bismuth and tin constitute the main group of alloying elements for zinc baths used hot dip galvanizing. These metals improve fluidity liquid zinc, which positively affects consumption improves appearance coating. However, their presence in bath, despite beneficial effects, is controversial due to increased risk metal-assisted cracking (LMAC). Recent studies also indicate t...
