Corrosion Testing Services

During the materials selection process for an industrial application, an evaluation of different  materials and how they react in a specific operating environment is required. Exposure of materials to simulated corrosion circumstances provides the following analytical data:

  • Estimated Service Life/Durability
  • Comparison of Candidate Materials
  • Performance Expectations in Operating Environments
  • Material Suitability to Final Applications

IMR operates several pieces of equipment capable of replicating natural environmental and atmospheric conditions involved in cyclic testing; modeling structure, morphology, and relative corrosion resistance. 

IMR Test Labs corrosion testing methods provide quality control by ensuring that your component surface protection application processes, such as coatings, anodizing and electroplating are being performed to specification.

Types of Corrosion Testing Services

Accelerated environmental weathering methods like ASTM B117 salt spray, passivation testing, and cyclic corrosion are performed at defined intervals, utilizing temperature and humidity controls.

Electrochemical Corrosion Testing is performed to ASTM G199 through a controlled electrochemical reaction between two materials, or between an exposed surface and its operating environment.

IMR's metallurgical team is equipped to identify corrodents and other environmental variables that are directly responsible for intergranular corrosion attack, per ASTM B117.

Types of Corrosion

Uniform or General Corrosion

The most common type, general corrosion occurs when widespread exposure to weather, chemicals, or other elements causes corrosion across the entirety of an exposed metal surface.

High-Temperature Corrosion

Corrosion is sometimes caused in specific types of metals when there is exposure to corrosive substances at high temperatures.

Local Corrosion

Local corrosion occurs when only a specific area is affected, such as a crevice or hole, however it threatens the integrity of the entire metal surface. 

Alloy Corrosion

Corrosive elements target one component of an alloy.

Galvanic Corrosion

Two distinct types of metal come into contact with one another and an electrochemical reaction causes one of the metals to corrode faster.  

Environmentally Assisted Cracking (EAC)

Stress-environment interactions cause corrosion, such as stress corrosion cracking, caustic cracking, environmental stress cracking, and other subtypes.  Stress, chemical exposure, pressure, vibrations, welding, machining and other factors can cause EAC.

Flow-Assisted Corrosion or Erosion-Corrosion

Corrosion caused by the flow of water or air, exposing fresh metal, which can rapidly degrade components. 

Fretting Corrosion

Occurs when surfaces wear down from constant friction caused by vibrations or rubbing. 

Corrosion Testing Services - FAQs

How long does corrosion testing take?

Corrosion testing is designed to simulate anywhere from a few months to several years of natural exposure.  A ratio of number of hours to natural exposure time is followed and can vary depending on the material being tested and the natural exposure that is being simulated.  

What environmental factors does corrosion testing simulate?

Corrosion testing simulates weather elements such as rain and fog, ocean spray, UV light exposure, temperature, wind-borne particles, and pollution.  

What is the main benefit of corrosion testing?

Corrosion testing provides key insight into material’s susceptibility to it’s environmental exposures therefore allowing the end user to evaluate whether it is correct for the application, if it will perform as expected, or if an alternate material is more suitable.
