Summary: | The aim of this study was to investigate the
corrosion behaviour of annealed stainless steel mesh. Thermal oxidation
treatments were applied to steel mesh in a muffle furnace at 500 ᵒC, 700 ᵒC and
900 ᵒC. Surface morphology of annealed and non-annealed stainless steel meshes
was compared before and after polarization. Roughness of the steel surface was
increased after heat-treatment. The corrosion properties of non-annealed and
annealed steel were determined using linear sweep voltammetry. The corrosion behaviour
of annealed stainless steel was examined by means of a potentiostat in a 3.5
wt.% NaCl, 1 M H2SO4 and 1 M KOH electrolytes. The corrosion susceptibility of heat treated
stainless steel was more than that of non-heat treated stainless steel in
alkaline electrolyte. While pitting corrosion of non-annealed and annealed
stainless steel was different, corrosion potential and current of steel mesh
without heat treatment was the same as the steel meshes annealed at 500 ᵒC and
700 ᵒC. Corrosion current and corrosion potential of non-annealed steel was the
same as 500 ᵒC annealed steel mesh in acidic medium. |
