Microbial corrosion and cracking in steel. Results from a screening of soil corrosivity using weight loss coupons

摘要

A series of field measurements (49 in all) of the corrosion rate on steel exposed in different types of soil has been conducted by means of weight loss coupons. Additional measurements included pH, open circuit corrosion potential (OCP), soil resistivity, and analysis of the chemical composition of the corrosion products formed during the exposure. A brief discussion of the corrosion rate dependency on these additional parameters has been presented. (au)
