The Use of Nanoporous Oxide Coatings on Steel Strand for Decreased Corrosion and Improved Adhesion

The effect on corrosion resistance of inorganic nanoparticle coatings on steel strand used in transportation infrastructure is studied by means of electrochemical methods. The strand is coated with zirconia oxide (ZrO2) and titanium dioxide (TiO2) sol-gels by dip coating process. Linear Polarization measurements of bare and coated strand are taken and analyzed to obtain an optimum coating process. The steel-concrete bond of coated strand is evaluated through small-scale pull-out tests of sire embedded in mortar cylinders. Lastly, the effect on the mechanical behavior of the strand due to the coating process is assessed by the mechanical properties obtained from tension tests of treated versus untreated wire.
