This paper describes the correlation between the value of the corrosion potential and various types of corrosion of metals and alloys and their welded joints. It is shown that using the method of electrochemical noise is possible to predict the tendency of metals and alloys and their welded joints to different forms of localized corrosion (e.g. pitting corrosion), on the basis of the corrosion potential value. Also, there is a correlation between the value of corrosion potential and the tendency of aluminum alloys to stress corrosion cracking. The correlation between the value of the corrosion potential and the type of corrosion inhibitor is presented. In addition, the correlation between corrosion potential and tendency of stainless steels to pitting corrosion, as well as the tendency of surgical implants to galvanic corrosion was considered. Criteria for sacrificial and active cathodic protection are based on the measurements of corrosion potential. Also, the corrosion behaviour of steel armature in concrete depends on the value of corrosion potential. The susceptibility of metal (steel) constructions and their welded joints to hydrogen embrittlement depends to a considerable extent on the corrosion potential of steel in the given corrosion environment. Due to a large number of applications of corrosion potential measurements, this study is divided into two parts (Part I and Part II). |
