Abstract

NiCrAl composite coatings were obtained by electro-deposition under direct current (DC) conditions from a Watt’s bath containing suspended Cr, Al particles. Mathematical models were developed to simulate the electroplated composite coating. The models allow composition of the coatings to be predicted. The predicted values obtained were close to the experimental values, indicating the suitability of the models. The prediction made using Response Surface Method (RSM) was also supported by SEM photos. Three-dimensional surface plots were helpful for predicting results by performing only limited set of experiments.
