Metallographic Consulting And Lab Services 

In our own modern metallography laboratory, the coating quality can be directly assessed on the cross sections. The coating porosities can, for example, have a strong effect depending on the material selection and spraying method and have to be adjusted to the application.  With the several coating systems used by Nova Werke AG, coating porosities of less than 1 vol-% up to approx. 40 vol-% can be achieved. Fused layers consisting of self -fluxing alloys, on the other hand, are absolutely dense. It is also possible to seal sprayed coatings by filling the residual pores and capillaries with a corrosion-proof medium.
