Corrosion resistance and optimal surface roughness are essential aspects for efficient maintenance and cleaning of food machinery. We therefore always apply proven and functional pickling and surface passivation procedures. In the FK system, we prefer blasting as the final treatment for a surface, with an emphasis on process cleanliness and minimizing surface damage.

Ra in the range of 0.4-1 μm is ideal to eliminate the risk of bacteria adhering to the surface. Achieving this roughness with conventional blasting is challenging, so the demands on surface treatment are increasing. Our technologies allow for roughness up to Ra 0.8 μm.

We cooperate with the University of Chemistry and Technology Prague to research the corrosion resistance of various surface treatments. The results so far show that blasting cleanliness significantly affects protection against spot corrosion. The full results will be definitive in 2026.
