Effect of liquid zinc on Armco iron with relevance to pots used in galvanizing

The present investigation deals with the comparative study of liquid zinc attack on Armco iron and Tisco A grade iron within a temperature range of 450°C to 550°C. The effect of variables, e.g. time of contact, temperature, on weight loss of iron for a similar geometry of specimens has been studied and discussed. The maximum weight loss of iron has been found at 500°C for both the irons. It has been observed that even a slight variation in silicon content (on increase) appreciably increases the rate of attack on iron.
