DC105™ DC Corrosion

The DC105 DC Corrosion Techniques Software provides proven electrochemical techniques to investigate corrosion problems, extract mechanistic information, and predict long-term corrosion rates from an array of experiments. The DC105 runs standard DC corrosion tests such as polarization resistance, cyclic polarization, and galvanic corrosion in addition to a number of others.

Overview

Overview

The DC105 DC Corrosion Techniques Software is a powerful package containing a wide assortment of electrochemical experiments for corrosion evaluation. With the click of a button, users can run standard corrosion tests such as polarization resistance, cyclic polarization and galvanic corrosion. Experiments can easily be strung together using the Gamry Sequence Wizard to create automated sequences of experiments for more efficient corrosion testing. DC105 is compatible with all Gamry Potentiostats. Analysis is carried out with the Gamry Echem Analyst in order to extract long-term corrosion rates and evaluate material performance. For higher experimental throughput, DC105 experiments can be multiplexed with the ECM8 Electrochemical Multiplexer.

Features

Corrosion Analysis with Echem Analyst
DC105 includes analysis scripts that work with Gamry’s Echem Analyst software to appropriately display the results of corrosion measurements. For each experiment users have access to tools for Tafel fitting, polarization resistance, integration, min/max, and post-run iR correction.

Increased Throughput
DC105 includes special experiment scripts designed to maximize the potential of the ECM8 Electrochemical Multiplexer. These experiments allow users to run long-term experiments across 8 electrochemical cells sequentially. Corrosion potential, galvanic corrosion, Rp/Ec trend, galvanodynamic, potentiodynamic and potentiostatic are specifically designed to increase throughput by utilizing the ECM8, however, users can build a custom battery of tests to work with with multiplexer using the Gamry Sequence Wizard.
