Comment la tomographie a rayons X améliore la sécurité et la fiabilité des freins de votre bicyclette électrique ?

The aerospace industry encounters several product quality problems because of the complexity of the parts used. From turbine blades, pitot tubes, cast parts to electronic sensors, the challenges are numerous and the industry is very demanding of improving part quality as security is crucial. For any shape or form of aerospace parts, X-ray CT is effective to check-in product quality, develop improved parts by taking into account security, waste reduction, environmentally friendly materials and most importantly inspecting without destroying the part.

First, let’s discover all the components that form the braking system :

Leviers

Les appendices qui se fixent sur vos poignées et servent de système d'activation de vos freins sont appelés leviers.

Étrier

L'étrier est l'unité de logement principale pour deux autres composants de freinage importants : la plaquette de frein et les pistons. Les pistons se déplacent lorsque l'on tire sur le levier, pressant ainsi la plaquette de frein contre le rotor de frein. Les plaquettes de frein sont conçues pour ralentir l'E-bike en exerçant une friction sur le rotor de frein tout en absorbant la chaleur générée par le rotor de frein lorsqu'il est pressé contre lui. Lorsque votre système de freinage ne fonctionne pas correctement, le premier composant à remplacer est la plaquette de frein.

By getting the most out of your CT system, you’ll be able to improve product quality, reduce time-to-market and drastically reduce the inspection costs in your facility.

NANO-CT – VERY HIGH-RESOLUTION FOR R&D APPLICATIONS

The best way to get a 3D rendering of H2 electrodes Nano-CT is very useful to image at very high resolution the 3D microstructure of the anode-electrolyte stack. The stack of proton-exchange membrane fuel cell (PEMFC), also known as polymer electrolyte membrane (PEM) fuels cells are where the electrochemical exchange of the reactant gases hydrogen and oxygen produces electricity. The µCT allows to observe defects inside the volume of these stacks and to show their evolution after the electrochemical reaction. A better understanding leads the way to better anticipation of defects.
 
X-ray nano-CT is a powerful method to get a 3D rendering at a very high resolution of the internal electrode microstructure. X-ray nano-tomography, also called nano-CT is a high-precision 3D rendering technology with sub-micron resolution. This concept is based on further development of existing micro-CT technology. Parts' structures at a cellular level become obvious when the spatial resolution improves. The term nano is used to highlight that the pixel sizes of the cross-sections are in the nanometer range, hence this new method is definitely called Nano-CT.
 
Nano-CT is of interest to scan at very high-resolution the 3D microstructure of anode-electrolyte in an electrochemical cell, as well as the reduction behavior. X-ray CT helps to understand and correct the manufacturing process and get the best returns with such cells.
 
In case of a brake calliper fluid leak, X-ray CT enables to visualize the leak in a non-destructive way. It is even possible to put the calliper under constraints, adding pressure for example using an external device. Several parts through-holes allow monitoring from the outside an experimental setup.
 
Below is a view of Y slices with and without the colored rendering of the internal structure.
The addition of colors in the 3D rendering is one of the possibilities of X-ray computed tomography but another possibility is the addition of geometries on interesting features. Measuring diameters, concentricity, cylindricity and so many others parameters.

Benefits of inspecting aerospace components with X-ray CT  

-   Non-destructive technique to avoid losing key information by cutting the parts 
 
-   X-ray CT is independent from the sample complexity and offers accurate results for any parts’ shape or form… 
 
-   Simple operations with fast scans save cost and time 
 
-   Early defect detection saves costs, ensures security, reduces waste, and warranty & reclaim issues 
 
-   Inspection for various aerospace components from cast parts to composites 
 
 
With more and more components having complex multi-material structures, finding out whether a part is reliable and achieves conformity restrictions is difficult with traditional testing methods. That is why for aerospace components, X-ray CT offers new inspection alternatives as an all-in-one non-destructive technique representing a 3D model with greater image quality – all while being fast, accurate and automatic.
