This work is a study of the behavior of steel rebar coated by electroless nickel in chloride-contaminated concrete. The steel rebars were coated in an electroless nickel bath for 1, 2 and 3 hours. They were then subjected to heat treatment at 400 C for periods of 1, 2 and 3 hours. The nickel-coated rebars were embedded in concrete samples with NaCl concentrations at 0.00; 0.10; 0.15 and 0.20 %, based on concrete weight. Their behavior was evaluated by measurement of potentials, polarization resistance, potentiodynamic polarization curves, electrical resistance and visual inspection. Corrosion rates were less than 0.01 {micro}A/cm{sup 2} after 40 months` testing.
