Description

Elsyca CorrosionMaster is a CAD based software platform for simulating the inherent corrosion susceptibility of assemblies of various substrates and/or metallic coatings.

Elsyca CorrosionMaster identifies corrosion hot spots and predicts corrosion rates. The engineer can quickly evaluate design alternatives to improve the functional life, and can judge the difference in corrosion life depending on the environment in which the product will be operated (for example coastal versus inland).

This is not a simple look-up of galvanic potentials. The technology is based on FEA (finite element analysis) techniques solving for the potential distribution in a thin film over the surfaces of the assembly as a function of material/environment polarization characteristics.

As of October 2017, the Elsyca CorrosionMaster platform tool was extended with the brand-new Crevice Corrosion module. When it comes to crevice corrosion, local geometrical effects start playing a role: access to oxygen is limited within the crevice, concentration changes cannot be neglected anymore, etc. Hence, the macro-scale simulation approach was extended to the level of the micro-scale.
Elsyca CorrosionMaster – Crevice Corrosion enables modeling the local characteristics within the crevice, remaining at the same time robust and fast for a quick corrosion risk assessment.

Key Features

Key features are:

• models from any CAD package can be imported as STL grids;

• from component level to full assembly level models;

• automated high-quality meshing included – no user interaction required;

• allows thin films of arbitratry thickness (for corrosion cases under immersed conditions CPMaster is used) ;

• supports time stepping for accumulation of corrosion damage over service life;

• allows modeling of shape change due to corrosion;

• supports sacrificial coatings;

• includes model for paint degradation;

• includes Crevice Corrosion module;

• Elsyca XPlorer, the visualization and post-processing environment that allows sharing 3D simulation results with other stakeholders.
