Corrosion Testing


Corrosion costs industry and manufacturing billions of dollars annually.  Choosing the right raw materials and coatings, and understanding your in-service conditions can save you costly repairs, failures and recalls. 

The IMR corrosion testing lab helps you estimate component service life, compare candidate materials in your service environment, and helps screen your materials and their condition. Weathering testing also provides quality control by ensuring that your application processes, such as coatings, anodizing and electroplating are being performed to specification.

Corrosion testing services offered include accelerated weathering methods like B117 salt spray, passivation testing and cyclic corrosion, as well as metallurgical corrosion evaluation methods such as potentiodynamic corrosion, dezincification testing and mercurous nitrate testing.

Testing is performed through a controlled electrochemical reaction between two materials, or between an exposed surface and its surrounding environment.  The introduction of a voltage current to the testing setup rapidly accelerates the effect of the aqueous solution on the material. Therefore, targeted electrolyte solutions can be used to simulate long-term conditions and predict and characterize the corrosive properties of metal materials and components

How Can We Help?

Do you need quality checks to ensure your processes such as coating and painting are being performed to specification?  IMR offers a wide range of accelerated weathering methods such as salt spray testing, cyclic corrosion, gravelometer testing and QUV exposure. 

Do you need to compare candidate materials that will be implemented under harsh in-service conditions? Do you need to compare different materials, lots or suppliers? From slow strain rate testing to salt spray testing, we can simulate a wide range of environments. Our reports are concise and professional with clear side by side results so you can be sure you're choosing a high-quality material that will perform as expected.

Do you have parts that are failing under corrosive in-service conditions?  Let us compare old and new lots in your service environment to ensure the material is up to spec. Our failure analysis group has performed hundreds of failure analyses caused by a wide range of corrosion problems including microbially induced corrosion (MIC), pitting corrosion, dezincification, improper coating application and much more.
