Abstract

Ni-Al2O3 composite coatings were deposited over a mild steel specimens using electro co-deposition coating method. Composite coatings are prepared by conventional type of electro deposition using watts type of solution. The primary electroplating parameters of current density, pH value of electrolyte, temperature bath, amount of Al2O3 particles in bath and agitation speed were considered for experimental studies. The composite coated specimen surfaces examined by scanning electron microscope and studies showed that coating formed successfully on mild steel substrate, and showed that particles were uniformly dispersed in electro deposited Ni matrix. Corrosion and wear resistance tests showed much improvement in the mechanical properties of composite structure Ni-Al2O3.
