Corrosão

Eletroquímica Corrosão Oxygen is one of the most destructive forces in modern society, especially because we build and manufacture using metals.  From rusting iron rebar, to stress corrosion cracking on aluminum hulled craft, to the extremely corrosion resistant nickel alloys used for potential nuclear waste storage, corrosion happens.

Gamry has been at the forefront of electrochemical corrosion testing since our inception in 1989. Read on to learn more about corrosion research and how Gamry people and systems fit in.

Researchers looking at high throughput or materials selection are looking for easy-to-use, reliable systems, that give them the right answer.  Gamry has long been known as the market leader when it comes to instrumentation for corrosion testing.  Running ASTM testing is easy with our standard list of experiments – Polarization Resistance, Potentiodynamic, Cyclic Polarization, etc.  Our Sequence Wizard lets you string together experiments, click Start, and then come back when finished.

All of Gamry potentiostats are electrically isolated, allowing you to run experiments on grounded cells such as autoclaves.  High compliance voltages ensure adequate power when dealing with resistive electrolytes. 

Our analysis software allows for easy data workup, reporting and charting.  Easily compare results or export data for workup in another program.

Recommended Systems:

Routine ASTM G 59, G 61, F 746, or F 2129 Testing - Interface 1000A or 1000E (single or multichannel setups depending on throughput needs), Multiport, two Saturated Calomel Reference electrodes (one as a backup).  Gamry recommends the ECM8 Electrochemical Multiplexer if increased throughput at a lower price point is necessary. Note that the multiplexer runs experiments sequentially, not simultaneously. For very corrosion resistant systems (very low corrosion rates), Gamry recommends the Reference 600+ due to its low-current (60 pA lowest full-scale range) capabilities. 

If you are considering doing electrochemical impedance experiments, the Interface 1000E, Reference 600+, Reference 3000, and Reference 3000AE are all ideal instruments.  

Critical Pitting Temperature - Any of the above-mentioned instruments can perform critical pitting temperature experiments but you will also need a TDC4 temperature controller (or equivalent), FlexCell, heating mantle, stirring motor, and stirring rod kit.
