We offer you the most diverse types of surface refinement. Be it to improve the appearance of the products, to increase the durability under weathering or to reduce wear and tear under mechanical stress.
Surface finishing by FACO and our partners means: No additional ways, costs, delivery times.
Everything from one source! We organize it for you!
Electrogalvanizing provides corrosion protection, but can also be used to improve the appearance of components (decorative galvanizing).
In contrast to hot-dip galvanizing, the sheet is not immersed in a molten zinc bath but in a zinc electrolyte. In this case, the workpiece is the cathode, the anode is an electrode made of the purest possible zinc.
Due to the significantly lower layer thickness of only 3µm to 20µm, electrogalvanizing is not an option as protection for parts in outdoor use (outdoor weathering).
However, there are advantages when galvanizing sheets with finer perforations. The holes do not clog. Another advantage is that the sheets or grids do not warp due to the low temperature of the electrolyte of 20°C to 60°C!
Electrolytic polishing or electropolishing (also known as electropolishing) is an ablative manufacturing process. The electrochemical process is used for smoothing (by removing) components. In an electrolyte specially adapted to the material, the workpiece to be polished is switched as the anode with the addition of an external current source and material is removed from the surface free of mechanical stress. The material is removed over the entire component. The roughness is reduced and at the same time micro cracks and local stresses are eliminated. As the prominent peaks and burrs of the surface structure are preferably levelled or corners and edges are more strongly removed, the overall surface roughness can be reduced by the process. The result is a smooth, shiny surface. Electropolishing is effective in the micro range, while the structure and shape are retained in the macro range. Electrolytic polishing places no mechanical or thermal stress on the workpiece. The process is suitable for stainless steels with small amounts of non-metallic inclusions as well as steels, brass, aluminium or copper.
