A green Nano-ceramic reinforced thin film: Morphological and Electrochemical Study

Surface pretreatments are used on metal surfaces before application of organic paints for better adhesion and improved corrosion protection [1]. One such pretreatment process is theapplication of chemical conversion coatings. The advantages of Hexafluorozirconic acid based conversion thin film incomparison with former commonly used phosphate are: no need for frequent desludging, the energy input is lower because the solution temperature is near to room and lack ofdetrimental effect on ground water sources.
