INVESTIGATION OF THE MECHANICAL, CORROSION PROPERTIES AND WEAR BEHAVIOUR OF ELECTROLESS NI-P PLATED MILD STEEL

S. Ilangovan

Abstract: In the present study the mild steel (MS) specimens were coated with Nickel-Phosphorus (Ni-P) using acrylic bath. Heat treatment was carried out on specimens under different temperatures and time periods in an inert atmosphere. The various mechanical and tribological tests were performed on specimens. Using weight loss method, the corrosion nature of the samples under different environments was also studied. The results show that there was significant effect in mechanical and chemical properties of the plated specimens. The properties of the heat treated specimens increased significantly with modest loss in fatigue properties.

Keywords: Ni-P, surface coating, coefficient of friction, wear, corrosion, fatigue, hardness.
