The evaluation of Cerium based coating quality, reliability and suitability for insulator pin is governed by micro-structure analysis, hardness, adhesive strength between coating and substrate, surface binding energy, corrosion resistance as well as lifetime of coatings. After immersion in 60,000 PPM CeCl₃.7H₂O coating bath for 7 days, coatings consist of Ce rich dense protective film (24 ㎛). The Energy Dispersive X-Ray Spectroscopy EDS and X-Ray photoelectron spectroscopy XPS confirm 85.4% rise in weight (%) of Ce with immersion time. The Scanning Electron Microscope SEM and Vickers hardness test reveals cracks in coating film along with 1.5% decrease in microhardness with immersion time higher than 7 days. At the same time optimized coated specimens represent around 16.09% added hardness in contrast to bare specimens. The adhesive and interface strength of coating-substrate system are evaluated by X-cut Tape test and Cohesive Zone Finite Element approach CZM. The chemical bonding and binding energy intensity of coated specimens were investigated in detail by XPS. The lifetime expectancy of galvanised coating for coated specimens is 2.5 times more in opposed to bare specimens.
