Case of Damage Investigations

In the field of damage analysis we have many years of experience and efficient technical equipment to trace damage to coatings and composite systems back to probable causes.

Small defects in coatings can often be easily examined using a microscope. By supplementing microscopic methods with element or molecular analyses, the cause of damage can be further determined. For example, the delamination of a powder coating due to unsuitable or improper phosphating can be described in detail by combining SEM images and EDX spectrums. Unintentional delamination is often caused by inadequate cleaning or pretreatment or other deviations from "normally functioning" processes. Depending on the problem, surface contaminations are detected by analytical methods such as FT-IR, HPLC or GC/MS.

In other cases of damage, it may be useful to adjust the ambient and application conditions, e.g. to determine the effects of wet and damp storage on test bondings and to assess their influence.

The evaluation of the damage cases is carried out under consideration of the materials used, the selected process parameters and the application and exposure of the parts. In principle, it is always advantageous for a damage investigation to know as much as possible about the materials and processes.
If necessary, we also try to find ways of avoiding future damage and making processes more robust.
