Synthesis and characterization of Co-Mo alloy coating

Abstract

© Published under licence by IOP Publishing Ltd. Surface coating is very important in some applications. The preparation of Co-Mo alloy coating was prepared using electrodeposition process. The process of electrodeposition method was performed using 4 different concentration of molybdenum. The purpose of using different concentration of Mo in the solution bath is to find the optimum concentration of Mo that resulting to the best mechanical properties. The corrosion behavior, wear properties, surface morphologies and compositions of Co-Mo alloy was studied. The smooth surface was obtained when there was no Mo element in the solution bath. The Co-Mo coating that has the highest concentration of Mo, having the highest hardness value which is 286.6 HV. It was observed that the addition of Mo element in the deposit improved corrosion behavior of the deposits, hardness properties and resistance toward slurry erosion.
