A virtual instrument for quantitative assessment of pitting corrosion

Purpose The purpose of this paper is to develop a digital instrument for the quantitative evaluation of pitting corrosion in metals. Design/methodology/approach This investigation comprises two central parts: research, testing and monitoring of the formation of pitting by conventional methods applying ASTM standards and the development of a virtual instrument based on the LabVIEW 2010 platform. Findings The methodology used was suitable for the analysis of pitting in carbon steel and aluminum alloy UNS A96061, used in aerospace industry. Practical implications This technique allows to localize, measure and quantify pits on metallic surfaces, for corrosion control in the environment and industry. Originality/value This combination of conventional and digital methods will assist in corrosion control of pitting in industrial equipment.
