Sodium hexameta phosphate enhances the corrosion rate of steels. But in the prsence of calcium/magnesium metal ion it deaccelerates corrosion rate. Using 0.5% SHMP in presence of CaCl2 corrosion rate decreases. Corrosion rate decreases upto the addition of 10 ppm of CaCl2 solution.


Key words

White cast iron, sodium hexameta phosphate, calcium chloride, corrosion rate.
