Automatic measurement and Evaluation of panels for corrosion testing
According to DIN EN ISO 4628 – 8, corrosion test panels are often evaluated with visually and a use of a ruler or similar measurement devices. On one hand, this is quite a lot of effort, on the other hand, this procedure is unprecise.
Q-Chain® SuMo is a fully-automatic measurement device for the measurement of corrosion test panels, starting with the generation of measurement grids up to the automatic evaluation of these panels. The sensor type allows a detection of delamination as well as rust without further treatment of the test panel (scratching).
How does Q-Chain® SuMo work?
The measurement principle is based on impulse thermography, which can differentiate between delamination and rust. The signals differ significantly between adhesion and non-adhesion of a layer, which allows a precise differentiation.
The sensor is built into a X/Y machine (approx. 60 x 50 x 50 cm), which allows a grid in 0,15 resolution. The system does not require a removal of the delaminated layers and saves time for preparation, but also reduces the user influence by potential damages on the surface. It allows a multiple use of the corrosion panels and potentially a repeating weathering of the same sample.
There is also a device for automatic panel handling, which leads to a serial handling of the panels. The panels are labelled by barcodes or QR-Codes, which are read by an integrated camera. This makes it possible to match the results to the panel information in the database.
Evaluations e.g. according to DIN EN ISO 4628 - 8 contain more information than required. For example, areas with delamination and no rust (yellow) can be visualized against areas with rust (red).
This differentiation between delamination and rust can lead to further insights into the corrosion behavior of the system.
Software from ORONTEC – Easy and Flexible
RONTEC’s software for Q-Chain® SuMo enables the user to create measurement grids in an intuitive and easy way. These grids can be used for single panels or a series of panels. As usual, the Q-Chain® Database leads to a safe and unfiltered storage of measurement data. Open interfaces allow an integration into existing systms, the database can be run locally on the PC or in the intranet. Reports are saved in the MS Excel™ data format.
