Cyclic corrosion testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to outdoors in resulting structure, morphology, and relative corrosion rates.

Q-FOG cyclic corrosion chambers from Q-Lab can run traditional salt spray, Prohesion, and most cyclic automotive tests. Q-FOG chambers are available in two sizes to fulfill a wide range of testing requirements.

Q-FOG cyclic corrosion testers are the simplest, most reliable, and easiest to use corrosion testers available.

 

Cyclic Corrosion Testing
Prior to cyclic corrosion testing, conventional salt spray (a continuous salt spray at 35˚C), was the standard way to simulate corrosion in a lab.   Because conventional salt spray methods failed to mimic the natural wet/dry cycles of the outdoors, test results frequently provided poor correlation to outdoors. 

 

In a Q-FOG cyclic corrosion tester, specimens are exposed to a series of different environments in a repetitive cycle that mimics the outdoors.  Simple cycles, such as Prohesion, may consist of cycling between salt fog and dry conditions.  More sophisticated automotive methods may call for multi-step cycles that incorporate humidity or condensation, along with salt spray and dry-off.
