New procedure for electrochemical production of Ni–TiC composite powder

Abstract

Electrochemical deposition of Ni–TiC composite powder was investigated. The electrolyte was a commercially available Watts bath containing insoluble TiC particles. Titanium carbide powder with high purity was produced by combustion synthesis also known as self-propagating high temperature. The effect of particle size of carbide powder on TiC incorporation was also reported. The composition and structure were examined by X-ray diffraction and SEM analysis. The grain size was calculated by Scherrer formula using Xpert HighScore software. It was found that magnetic stirring produce more uniform distribution in the suspension. It has been observed that the amount of embedded TiC and thus hardness of composite powder increases with decrease in particle size of titanium carbide in the bath.
