Web1 apr. 2011 · A few researchers have also studied the influence of microstructure on the corrosion behaviour of magnesium alloys [6], [7]. Generally, the surface roughness plays a role on the corrosion behaviour of metallic materials. It has been reported that an increase in the surface roughness of stainless steels increases the pitting susceptibility [8 ... Pitting corrosion is defined by localized attack, ranging from microns to millimeters in diameter, in an otherwise passive surface and only occurs for specific alloy and environmental combinations. Thus, this type of corrosion typically occurs in alloys that are protected by a tenacious (passivating) oxide film such as stainless steels, nickel alloys, aluminum alloys in environments that contain an aggressive species such as chlorides (Cl ) or thiosulfates (S2O3 ).
