Nickel Corrosion

Nickel corrosion testing shows the susceptibility of the tested sample to intergranular attack, pitting and/or exfoliation corrosion. Accurate measurements of the susceptibility to corrosion of a particular material allows engineers and manufacturers to ensure the material will perform to specified parameters.

 

Corrosion testing can be performed to a variety of specifications and or customer requirements. Most often, testing is done by immersion in solution. Corrosive immersions may be either acidic or basic, and will last anywhere from 24 to 120 hours. Once the immersion cycle is complete, the sample is analysed by visual inspection or mass loss evaluation.
