• Pitting corrosion
• Virtual instrument
• Carbon steel
• Aluminum alloy

Purpose - The purpose of this investigation was to develop a digital instrument for the quantitative evaluation of pitting corrosion in metals.
Design/methodology/approach - This investigation comprised two central parts: research, testing and monitoring of the formation of pitting by conventional methods and applying American Society for Testing and Materials (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 on carbon steel and aluminum alloy UNS A96061, used in the aerospace industry.
Practical implications - This technique allows pits to be to localized, measured and quantified on metallic surfaces, for corrosion evaluation in atmospheric and industrial environments.
Originality/value - This combination of conventional and digital methods can assist in corrosion control of pitting in industrial equipment.
