Tungsten oxide (WO3) nanoparticles at various concentrations of 1.7×10-2, 2.5×10-2 and 3.4×10-2 M were electrophoretic deposited onto stainless steel surface for corrosion inhibition investigations with respect to concentration as well temperature by using potentiostatic polarization technique. Results obtained show that WO3 nano coating was used a barrier layer the protection in saline solution. The morphology examined Scanning Electron Microscopy (SEM).The results indicated these are good inhibitors. All curves yielded similar behavior pointing is controlled charge transfer process so dissolution mechanism does not alter due presence nanoparticles. Generally, increasing inhibitor temperatures leads an increase efficiency. Thermodynamic parameters calculated, energy activation data reaction decreased It likely adsorption WO3NP on chemical nature.
