Corrosion Resistance of Galvanized Steel in the Environment of a Bioreactor

Abstract

The article deals with monitoring the corrosion resistibility of welded materials in the anaerobic fermenter (bioreactor). The main goal of this research is to assess the change of hardness after degradation. The change of hardness occurs in the corrosion environment and it correlates with the corrosion resistibility of material. The purpose of this experiment is to recognize the possibilities of using the CMT welded materials in the defined environment. As an innovative technology the acoustic emission method is used for assessment of surface layer disruption during hardness testing. Aluminium alloy with galvanized steel (AluZinc) was used as an experimental material. The basic materials were welded by the filler material AlSi3.

Keywords: galvanized steel; galvanic corrosion; hardness measurement; CMT welding; bioreactor; acoustic emission
