Galvanic Corrosion Testing

Galvanic corrosion occurs due to two different metals in contact with each other in the presence of corrosive electrolyte solution. When two metal materials forming a galvanic couple, the metal that has a more negative electrode potential corrodes slower than normal while the more active and anode one is greatly corroded.

STEMart carries out professional galvanic corrosion testing to provide necessary data to help you select the right materials combinations for your required application.
