Corrosion Testing Services

Corrosion is the degradation of materials due to chemical and electrochemical reactions of metallic components and products induced by stressors like humidity, sweat, rain, and salt. Corrosion testing is the evaluation of a material’s corrosion behavior in service conditions via routine electrochemical testing or long-term combined simulated environmental testing. It is critical during raw material selection, product design, and end-product testing. Corrosion testing is an integral part of pre-emptive monitoring of product degradation to avoid failure. It is essential in the development of corrosion-resistant materials and coatings. It is employed in a wide range of industries that are continuously exposed to corrosive environments, including HVAC, energy, transportation, electronics, and bio-materials.

Corrosion testing services encompass electrochemical corrosion tests, accelerated weathering tests, metallurgical corrosion evaluation, etc. in testing labs. Tests are standardized to evaluate material or product degradation in metals, polymers, and coatings among others. Specialized studies using microscopy, chemical analysis, and other physical or analytical techniques performed in a laboratory are utilized for the material’s in-depth corrosion characterization. Dynamic autoclaves, flow loops, and corrosion-resistant, and high-pressure vessels are some of the equipment used for corrosion testing. 

To examine the corrosion on a piece of steel, there are two typical testing techniques:

• Ultrasonic Testing: it is a non-destructive test that may detect internal steel faults and thickness changes with an extremely high degree of sensitivity. To find out if corrosion has changed the sound signature of the object, which would indicate corrosion has happened, very brief ultrasonic pulse-waves are transmitted into the steel.
• An electron beam is focused on a surface via a Scanning Electron Microscope (SEM), and when that beam is reflected back, it reveals discernible details about the sample’s topography and surface state. Applications include seeing microcracks and determining the material’s molecular make-up or coating are common.

Because of the quicker results, accelerated corrosion testing is frequently employed; however, because it is challenging to construct the test to take into account all potential corrosion mechanisms, the results may be compromised.

Our network of testing labs are well equipped to carry out corrosion testing and provide the best results to our clients based in the USA. We at Infinita Lab perform not only routine tests in the laboratory, but also perform designed custom tests in our testing labs as per the client’s specific requirements.
