CORROSION RESEARCH

CORROSION RESEARCH

Understanding the nanoscale processes that control corrosion initiation and propagation in bulk materials is a critical area of research. With Protochips’ workflow-based in situ TEM solutions, you can utilize the electron microscope to study structure-function relationships that govern underlying mechanisms leading to corrosion initiation and propagation.

CORROSION IN LIQUID ENVIRONMENTS – POSEIDON AX AND TRITON AX

Perform classic electrochemical analyses in a liquid electrolyte within the TEM 

Observe the root cause for behavior like pitting or chemical dissolution leading to defects that ultimately lead to material degradation in real time. Perform temperature-controlled electrochemical studies with Triton AX and room temperature electrochemical studies with Poseidon AX.

CORROSION IN HOT, HUMID ENVIRONMENTS – ATMOSPHERE AX

Apply high temperatures in humid environments to observe material behavior 

Observe the early stages of corrosion mechanisms, follow surface and grain boundary migration with elemental mapping, and control the sample environment with relevant temperature, pressure, gas, and humidity conditions.

THE PROTOCHIPS PHILOSOPHY

Each Protochips in situ TEM solution has been designed with three key goals in mind to ensure relevance of the results in a timely fashion.  

Scaling Bulk to Nano

Create a relevant experiment that is most comparable to bulk scale, whether it requires quantitative electrical measurements or humid, gaseous environments

Accelerating Productivity

Innovative designs and machine vision software lower the learning curve and streamline data collection and analysis

Fostering Collaboration and Discovery

Intuitive data processing platform provides transparency for collaborators, with a new way to visualize data for more productive discussions
