Parametric Analysis of Electrodeposited Nano-composite Coatings for Abrasive Wear Resistance
Description
Nano-composite coatings have become the focus of widespread research in recent years due in part to their superior properties when compared to purely metallic films. The benefits of using these types of coatings include high-specific heat, optical non-linearity, novel magnetic properties, enhanced mechanical behavior (large hardness and wear resistance), and good corrosion resistance. This chapter presents a parametric study of electrodeposited nano-composite coatings for improved abrasive wear resistance. The following physical parameters were investigated using a Taguchi L18 fractional factorial design of experiments (DOEs): current density, pH, bath temperature, nano-particle concentration, and electrolyte agitation (stir rate). The results were evaluated using the signal-to-noise (S/N) ratio to develop a non-dimensional relationship between the physical parameters and the abrasive wear resistance of the coating. The relationship showed that the abrasive wear resistance of the coating increases as the quantity of nano-particle in the solution and the agitation frequency increase. The analysis of variance (ANOVA) indicated that the particle concentration had the greatest significance to the wear resistance of the coating.
