Abstract

The electrochemical deposition and characterization on Hg containing ZnSe thin films are reported. Electrodeposition of ZnSeHg alloy coating onto aluminum substrates in a useful form from acid bath. The study of the electrochemical deposited alloys using electrochemical impedance spectral (EIS) and corrosion characteristics. The composition and structure of these alloys were investigated. The corrosion parameters determined from the polarization curves recorded in 0.5M NaCl solution at room temperature. The impedance spectra recorded at the ocp showed in all cases, which may be explained by the development of corrosion products on the electrode surface. The surface morphology of deposited films was investigated by scanning electron microscopy (SEM). The compositional analysis of electrodeposited films was investigated by Energy dispersive X-ray spectroscopy (EDAX).
