Metallography lab for microstructure analysis
At our in-house, state-of-the-art Nova Swiss® metallography lab, we can assess the layer quality directly from a material cross-section. Depending on the choice of materials and spraying process, the layer porosity (for example) can be strongly influenced and tailored to the respective application. The coating systems used by Nova Werke can achieve layer porosities of <1 up to around 40 vol.%. By contrast, fused layers are absolutely impervious. It is also possible to seal sprayed layers by filling residual pores and capillaries with a corrosion-resistant medium.
