Abstract
An important aspect regarding the sustainability of steel structures is to ensure the structure is protected from corrosion. A number of surface coatings are available that play an important role in protecting these structures. An important part of the management of these structures is reliable and regular inspection along with methods for early detection of corrosion processes. In this paper, a development and application of sensors for monitoring the steel coating degradation and corrosion damage to steel substrate are presented. An encapsulated corrosion kit with integrated EIS sensors and ER probes was developed. To test its efficiency, steel probes were coated with selected coatings in the laboratory and their performance was assessed under various aggressive atmospheres, including; salt, industrial and humid atmosphere.
Highlights
Many of the bridges and viaducts on the Slovenian rail network are more than 150 years old
The results of visual examination revealing the first signs of corrosion on different coatings and in different atmospheres are presented in Tab. 1
From Tab. 1, it can be observed that for the salt spray chamber, corrosion was detected for the primary coating and primary + intermediate coating and no corrosion was measured for the primary, intermediate and top coating case
Summary
Many of the bridges and viaducts on the Slovenian rail network are more than 150 years old. The corrosion kit was specially designed for the measurement of the corrosion properties of coatings and corrosion on the steel substrate covered by a protective coating 2 and 3 images of the development of corrosion with time of exposure for the primary coating on samples exposed in the salt spray and industrial chamber are shown. In Tab. 4 photos of the development of corrosion with time on samples with primary and intermediate coatings exposed in the salt spray chamber are shown. No corrosion was observed on any of exposed coated sensors in humid chamber
