Abstract

The present investigations construe study of Ni electroplating on AZ91 alloy in novel ChCl- ethylene glycol eutectic based ionic liquid using non-fluoride and non-chromium surface pretreatments and sandwiched electroless Ni-P layer. The electroplating employed Ce(NO3)(3) containing pretreatment offered highest corrosion resistance with corrosion current density similar to 0.9 mu A cm(-2) and sustained 10 h salt spray exposure without failure. The coating produced with Ce(NO3)(3) pretreatment showed highest critical load similar to 15.53 N and exhibited better adhesion strength than that produced using NiCO3. The coating performance is correlated with porosity index and NiP2 phase evolved after heat treatment.
