Reliable performance of materials is very important for safe and successful application any industrial process. Materials for a given application or equipment are selected for their required material properties, low initial capital investment, and minimum maintenance.  Changes in the process parameters to improve products can often lead to higher corrosion susceptibilities of the plant materials.  

The Corrosion and Materials Chemistry Research Laboratory (CMCRL) at the Georgia Institute of Technology, which is also associated with the Renewable Bioproducts Institute (RBI) have facilities to help industry with material selection and corrosion testing. Analytical and characterization tools needed for corrosion research are either available in our laboratory or as user facility at Georgia Tech.

CMCRL Equipment and Testing Capabilities

Here is a partial list of equipment and test facilities of the CMCRL at Georgia Tech:  

1. General Corrosion Tests (Room temperature up to 200oC)

2. Electrochemical Tests for general corrosion and localized corrosion:

a. Potentiodynamic Polarization, Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetery

b. Electrochemical tests at high temperatures and pressure (up to 300oC in autoclaves)

3. Erosion Corrosion – Rotating Cylinder Tests

4. Stress Corrosion Cracking and Corrosion Fatigue Testing

a. Slow Strain Rate Tests for stress corrosion cracking susceptibility of alloys at temperatures up to 200oC in corrosive environments, and 350°C in pure water.

b. Corrosion Fatigue test facility (MTS Model 810 machine with Teststar II® control system with environmental chamber) for crack growth and endurance limit studyin corrosive environments

5. High Temperature Gaseous Corrosion (Oxidation/Sulfidation Tests of Metallic Alloys)

a. Single and mixed gases over a range of temperatures, cyclic gases, and cyclic temperature capabilities (up to 1100°C)
