The following is a discussion of the article entitled “Reaction Rate Studies for the Corrosion of Metals in Acids, I. Iron in Mineral Acids” by P. B. Mathur and T. Vasudevan, Published in Corrosion, Vol. 38, No. 3, p. 171 (1982) March.
DISCUSSION by F. B. Growcock and W. W. Frenier, Dowell Division of Dow Chemicals U.S.A., Tulsa, Oklahoma.
The need for detailed gasometric corrosion studies is great. We commend the authors for their investigation of the effects of pH and temperature on the corrosion of mild steel in HCl, H2SO4, and H3PO4. Their HCI data compare quite favorably with data gathered in our laboratories on other carbon steels. However, several aspects of the study raise questions that should be considered:
We addressed this problem by performing least squares regression analyses of their data (Taylor series expansions would have proved a little...
