Enhanced corrosion efficiency of low-carbon steel was achieved by newly developed hybrid
multilayers, composed of low-carbon steel coated with an electrodeposited zinc sublayer (1
µm), a chitosan (CS) middle layer and ZrO2 coating by the sol–gel method (top-layer). The
middle chitosan layer was obtained by dipping galvanized steel substrate in 3% tartatic acid
water solution of medium molecular-weight chitosan, composed of β-(1–4)-linked D-
glucosamine and N-acetyl-D-glucosamine with a deacetylation degree of about 75 …
