The Corrosion Imager

Simplicity

The corrosion imager is a plug-and-play hardware and software package. Simply place your sample and press record!

Speed

Detect corrosion up to 10x earlier than with conventional methods.

Quantitative optical measurements for the inspection of corrosion protective surfaces

The development and quality control of coatings starts in the laboratory where coated test-panels are exposed to corrosive conditions. The coatings slowly degrades and corrosion processes start to occur on the test-panels. These changes are manually and visually inspected once the samples are removed from the measurement. This visual inspection requires a trained eye, especially because degradation and corrosion processes occur very slowly and at microscopic levels. This makes the manual inspection difficult and a challenging way to obtain objective and quantitative measures of degradation and corrosion that have occurred over a period of time.

The corrosion imager optically inspects the test-panels in real-time while they are exposed to corrosive conditions. The corrosion imager will automatically detect degradation and corrosion up to 10x earlier compared to conventional methods thanks to the high resolution optics and image recognition software. The corrosion imager will continuously monitor the evolution of degradation and corrosion while the sample is exposed to the corrosive environment. A degradation report and time-lapse video is created once the measurement is finished. This report contains detailed information on the development of different corrosion processes and can be used to optimize the coating formulation, check quality standards, or make promotion material for the end-customer who want to apply your coating formulation.

REAL-TIME OPTICAL INSPECTION

The corrosion imager allows the inspection of corrosion and degradation processes at an exposed surface of 10 cm2 at with an optical resolution of 15 microns per pixel.  This allows you to capture the very first signs of degradation before it’s even detectable with the human eye. The corrosion imager continuously monitors the optical changes that are occurring on the test-panels. This allow you to determine the starting-point and location where the degradation has started and helps you to predict how fast it will grow over time. 

The integrated bright field illumination of the corrosion imager enhances the contrast of the images, highlighting the smallest changes on the test-panels such as delamination, filiform corrosion and blister formation.

A VERSATILE CORROSION CHAMBER

The corrosion chamber is made from chemically resistant polyacetal and can be filled with 90 mL electrolyte of your choice to promote the corrosion processes in a controlled way. Optionally, an external reservoir of electrolyte can be attached to the corrosion cell to create a continuous flow of fresh electrolyte. The corrosion chamber is easy to clean and contains a drain to remove the remaining electrolyte once the measurement is finished.

Combining optical and electrochemical measurements at the same time highly improves the interpretation of electrochemical impedance spectroscopy, electrochemical noise, and cyclic voltammetry measurements. The corrosion chamber is equipped with two Ø 12 mm holes for your reference and counter electrodes. 

SOFTWARE FOR DETAILED ANALYSIS

The correlimage acquisition software lets you determine how many pictures and how long you want to measure. The software gives real-time information and a time-lapse video that shows you all the optical changes that are occurring while you are still recording, helping you to decide if you want to stop or continue the measurement. 

Get the most out of your measurement using the Correlimage analysis plugin. The software is equipped with the latest image recognition procedures to select, isolate and quantify all the degradation processes that have occurred on your sample over time, such as blistering, delamination, pitting and red rust. Export all your result to a degradation document in PDF containing pictures, or save all your data as a time-lapse video to prove that your coating meets the required quality standards.
