Studies on nickel diamond electro composites with modeling and optimisation perspective

Abstract

In the modern manufacturing systems there are two opposing newlinetechniques in the tool industry namely dry and high speed machining In newlinethese more heat is produced than in normal machining necessitating high hot newlinehardness To have good heat isolation between the chip and tool body special newlinesurface modifications of the tool materials are required Composite coating is newlineone of the surface modification techniques which enable to produce the newlinedesired properties of a tool material newlineComposite electroplating has been identified to be a simple and cost newlineeffective technique for the preparation of such kind of composites Electro newlinecomposites offer unique synergistic properties which can not be obtained by newlineany single metallic coating They enhance the wear resistance and hardness newlineof the base metal on the surface thus offering increased life newline newline
