Filmic Contamination Leads to Gearbox Failure

The determination of the technical cleanliness according to VDA-19.1 or ISO-16232 is now an integral part of quality control and error analysis - because the cleanliness of components is decisive for the quality and error-free function of the product. In addition to particles, filmic contamination poses a problem, as the following example from quality assurance in the manufacture of electric drive systems shows.

Filmic Pollution Decoded

The smallest contamination, not visible to the naked eye, leads to errors in the processing of components. One of our customers had this experience when coating a turned part: an unknown filmic contamination that was discovered on the component after washing hindered the coating process. Our laboratory team examined the contamination using Raman spectroscopy.
