EMD Technologies, LLC offers high quality testing and consultations services at a competitive charge. ASTM procedures are followed to carry out the tests.

 Corrosion Testing

 Electrochemical corrosion testing:

 We can carry out electrochemical corrosion tests in both aqueous and non-aqueous media by employing the following techniques:

•  Polarization (linear, anodic and cathodic)
•  Cyclic polarization
•  Potentiostatic / galvanostatic
•  Electrochemical impedance spectrometry
•  Electrochemical reactivation (EPR)
•  Slow strain rate testing (stress corrosion cracking)

The tests can also be carried out at elevated temperatures.

 Hot Corrosion Testing:

 We can carry out hot corrosion tests in specific environments also using conventional gravimetric (monitoring weight change of the specimens) techniques. The controlled environments can be varied by purging with gases such as oxygen, nitrogen, argon, hydrogen, and carbon dioxide. We can also handle sulfur dioxide. We can carry out electrochemical impedance spectroscopy at elevated temperature.

 Mechanical Testing

 We can carry out the following tests:   

•      Tensile testing (temperatures up to 1100^oC)
•      Constant load creep testing
•      High cycle/low cycle fatigue testing
•      Fracture toughness
•      Crack growth rate evaluation
•      Hardness
•      Impact toughness

Microstructural Evaluation

 We can carry out an extensive microstructural characterization using the following microscopic techniques:

•      Light optical microscopy;
•      Scanning electron microscopy;
•      Transmission electron microscopy;
•      Atomic Force Microscopy; and
•      Kelvin Probe Force Microscopy
