摘要: Empirical correlations that enable fast estimation of maximum and average pit depths pitted area percentage from the standard 3D surface parameters obtainable with infinite focus microscopy were established in this study. Carbon steel coupons by sulfate-reducing bacterium Desulfovibrio vulgaris used as specimens. The first determined laborious measurements individually manually identified pits on specimens then basis for developing correlations. A four-phase diagram, depth y-axis x-axis, was proposed an effective visual tool to categorize varying pitting risk patterns. study results afford more effective, quantitative characterization corrosion.
