摘要：
Polyethylene glycol (PEG)- and polydimethylsiloxane (PDMS)-based corrosion protection coatings of the AISI 316L stainless steel surface were investigated. X-ray photoelectron spectroscopy (XPS) was used to confirm successful deposition of the coatings on the substrate as well as to estimate the thickness for both coating types. Contact angle measurements were used to evaluate wetting properties of noncoated, PEG-coated, and PDMS-coated substrates. Hydrophobicity was achieved by applying PDMS coating on the substrate. Potentiodynamic measurements established enhanced corrosion stability of PEG-and PDMS-coated stainless steels. Electrochemical impedance spectroscopy was also performed. It showed superior corrosion protection vs immersion time dependence for PDMS coating in NaCl solution compared to PEG coating.
