Study of Surface Mechanical Properties of Electrode Posited, Shot Peened Copper Coating on Mild Steel Substrate

In this experimental work, thin film of copper coating were prepared from the Copper Sulphate bath with the aid of Electrolyte Deposition process over a cold rolled mild steel plate and mild steel round rod substrate. In this experimental process different parameters such as voltage, agitation speed and time of deposition were considered. Electrolyte deposition done before and after the shot peening process. After the electrolyte process the shot peening were done on the electrolyte deposition specimens and normal mild steel specimens. Fatigue test was conducted by the R R Moore bending test instrument under the pay load of 150 kg. Tensile test was conducted by using Universal Testing Machine. The micro hardness of the specimens were examined in the Vickers micro hardness tester under the pay load of 2 kgf. The surface morphologies of the specimens were investigated with Scanning Electron Microscopic analyzer. The surface roughness of the specimens were examined by the Tally Surf Gauge instrument.
