Measurement of corroded radiators

Engine cooling highly depends on the quality of radiators and materials resistance in terms of defects such as corrosion. Detailed knowledge about the effects of corrosion optimises the manufacturing processes of high quality engine cooling systems.

The German manufacturer Behr, a leading OEM supplier for vehicle air conditioning and engine cooling in passenger and commercial vehicles, is using the InfiniteFocus to achieve improvement in quality and lifespan. This is being achieved by accurately assessing the material composition and the affects on the production process.

The coolant in the radiator is replaced by corrosive substances to analyse the effects of corrosion on aluminium components and is then, using I, able to measure pittings of the surface.

Material loss caused by corrosion can be numerically verified with InfiniteFocus. ISO conform measurements such as profile, volume, area and roughness help to measure the corrosion distribution leading to a better understanding of how the material is affected during its life.

Also, InfiniteFocus is the only measurement instrument that simultaneously captures the entire surface topographic information that is directly registered with its true colour information. 3D measurements are performed directly on the optical image and the visual link between the surface and its 3D information enables far more precise and flexible measurement.
