Abstract
Investigations into the corrosion protection on edges of steel constructions -Results of laboratory investigations (Part 2). Based on laboratory tests, the corrosion protection capability of organic coating systems on edges of steel constructions was investigated. The edges were rounded with different mechanical and thermal tools. Three different coating systems were considered, whereby one of the systems was a so-called edge retentive system. Three criteria were utilized in order to assess the corrosion protection capability: edge coverage degree, barrier resistance of the coating systems, and an anticorrosive effect. The tests included DFT measurements on edges and areas, electrochemical impedance spectroscopy (EIS) measurements and accelerated ageing tests in a wave tank simulation chamber. Part 1 of the paper covered the general experimental design and details of the experimental procedure, whereas the present Part 2 reports about results of the test programme.
