The electrochemical nature of the corrosion process renders the use of electrochemical techniques interesting to investigate, measure and quantify corrosion phenomenon. Besides the accelerated corrosion tests performed in environmental chambers, our lab is equipped with electrochemical testing equipment (potentiostat) which is used for the examination of general, pitting, repassivation, galvanic behaviors or paint and coating performances through techniques such as linear polarization, cyclic potentiodynamic polarization, galvanic current measurement and monitoring (ZRA), electrochemical impedance spectroscopy (EIS) or electrochemical noise measurements (ECN and EPN).
Known as a form of corrosion that could cause catastrophic failures of critical assets even under low residual tensile stress for a susceptible metallic material, stress corrosion cracking (SCC) is difficult to predict and identify. SCC is a failure mechanism that requires the simultaneous action of a corrosive media and a sustained tensile stress. In some cases, SCC may occur in combination with hydrogen embrittlement.
To evaluate SCC or Hydrogen embrittlement, our team will use different chemical attack and condition as per ASTM G30, ASTM G103 or ASTM G36, and will perform Slow Strain Rate Testing (SSRT) according to different standards (e. g. NACE TM0198, NACE TM0111, ASTM G129 or ISO 7539-7).

Used to evaluate the environmental durability of various metals and coatings, our versatile cabinet will combine salt spray with other environmental conditions such as controlled humidity, drying and wetting. This is achieved by performing standards salt spray and cosmetics cyclic tests such as ASTM B117, ASTM G85, ISO 7253:2001, ISO 9227-2017, SAE J2334, VDA 621-415, etc, or by customizing in-house cyclic test according to service conditions.
