Özet

The corrosion of zinc coated with tungstate, molybdate and phosphate were investigated in the 1 M NaCl solution containing different sodium oxalate with concentrations of 1 × 10-2 - 1 × 10-5 M. The corrosion of zinc uncoated and covered with protective layer in Na 2WO4, Na2MoO4 and Na 2HPO4 were investigated in 1 M NaCl + xM Na 2C2O4 solutions by using potentiodynamic and impedance methods. The corrosion rates of zinc are especially low in the NaCl solution containing low oxalate concentrations.
