Overview of Tutorial

CORCALC has been developed to aid the corrosion practitioner in transforming laboratory-derived corrosion data into corrosion rates values. The goals of the tutorials are to provide:
  • Background information on and guidelines for using each of the calculators
  • Summaries of the limitations and assumptions behind the experimental technique that can impact interpretation of the laboratory data and calculated corrosion rates
  • Appropriate format (units) for the entered data

The calculators that make up CORCALC are:
  1. Corrosion (penetration) rates calculated from mass loss of rectangular coupons
  2. Radius change from mass loss of a wire
  3. Corrosion (penetration) rate as estimated from current density as obtained from electrochemical measurements
Each of the tutorials can be accessed through the Table of Contents above. Supplemental information on best laboratory practices for the techniques themselves can be found in such resources as ASTM Volume 03.02, “Wear and Erosion, Metal Corrosion”; ASM Handbook Volume 13A, “Corrosion: Fundamentals, Testing, and Protection; Uhlig’s Corrosion Handbook”, 2nd edition; and the ASTM publication: “Corrosion Tests and Standards – Application and Interpretation”, 2nd edition.
