Effect of Gelatin on the Performance of Cerium-based Conversion Coatings
Cerium-based conversion coating process for corrosion protection is a potential replacement of chromates. However, there are still some defects such that the processing time is too long and the conversion coatings are not thick enough. The experiment proves that compared to non-added animal gelatin in corrosion-inhibiting cerium solution, the added one improves the deposition rate. After post-treatment process in phosphate, the surface morphology of the coatings is tested by scanning electron microsopy (SEM), the chemical composition of the protective films have been examined by energy-dispersive Spectrometer (EDS) and thickness of films is measured by coating thickness gauge.
