What started almost a century ago as buffer between railway cars has now become a universally applicable damping element for almost all industry sectors – also as a protective element against potential damages to buildings and industrial facilities caused by earthquakes.

This is part 3 of our series on surface treatments of components. Due to the great number of different chemical processes, we have split them up andexplored these processes in the previous article:

• Chromate conversion coating
• Phosphating
• Galvanizing
• Plating
• Black oxide.

This blog article covers the remaining chemical processes commonly applied for the treatment of component surfaces.

In ourfirst blog articlewe presented the most common mechanical processes for the treatment of component surfaces. In this second part, we address the most frequently used methods of chemical surface treatments.The decision as to which of the following treatments should be applied is predominantly influenced by design points of view, technical aspects and the intended appearance of the product.
