Abstract

cobalt-tungsten anano structure alloy coating was produced using Pulse Electrodeposition in 200 Hz pulse frequency from citrate electrolyte at 60 ° C. In this study the influence of cobalt ions concentration in solution and Duty cycle on crystal structure, grain size, Hardness and corrosion resistance of coating was investigated. Surface morphology and composition of coatings was examined by scanning electron microscopy (SEM) and (EDS) analysis. The crystallite size of the coatings calculated from the x-ray diffraction patterns using the Scherrer equation. Micro Hardness of the coatings was assessed using a Vickers micro-indenter. Results showed that electrodeposited coating at 0. 2 mol/l cobalt sulphate and 60% Duty cycle with 1A/dm2had optimum coating on 758 Hv. Annealing amorphous coating was produced at current density of 4 A/dm2 in high vacuum pressure makes crystalline coating. Increasing temperature at 600° C makes a well-developed polycrystalline structure of Co3W and CowO4 in the coating. MicroHardness of coating increased from 436 Hv to 1059 Hv after heat treatment at 600 ° C. heat treatment of coating improved the corrosion resistance of coating. The coating heat treated at 400 º C had minimum corrosion rate.
