Corrosion of buried metal structures has mainly been evaluated by the physical and chemical characteristics of a soil. The electrochemical monitoring of the above objects is becoming popular.
This paper reviewed the recent progresses and the trend of corrosion monitorings in soils mainly by electrochemical techniques, which included such measurements as corrosion potential, galvanic current and polarization resistance. Fifty nine papers refered in this article were mostly selected from Chemical Abstracts. In the present state, the corrosion potential measurement seemed to deserve the practical field applications.
A number of attractive trials were found in the refered papers. This article (Part I) describes the direct monitoring of buried metal structures in the field and the corrosion monitoring with probes. The next article (Part II) describes the correlation of the corrosion rate with a few variables such as corrosion potential, soil resistivity and others.
Depending upon the reviewed articles, the authors proposed a systematic way of assessment regarding the underground corrosion of metal structures.
