Abstract

On the surface of low-alloy steels galvanized by different processes, environmental friendly rare-earth metal content layers had been deposited with different immersion times, in order to provide temporary corrosion protection. The morphology of formed conversion layers had been examined with atomic force microscope and the chemical structure had been examined by photoelectron spectroscopy. It had been stated, that the CeCl3 treating was the best among of the applied Ce(NO3)3, CeCl3 and LaCl3 saline solutions for all type of galvanized steel plates. Corrosion protection properties of conversion layers had been examined by electrochemical methods (polarization measurings, impedance spectroscopy). It had been stated that the best long life protection can be reached on continuous hot dip galvanized steel plate with 40 minutes CeCl3 treatment.
