Galvanic Structure, Layer for Layer
Galvanizing is more than just perfect appearances. Technically advanced pre-treatment and stratigraphy of the process ensure reliable corrosion and wear protection. Steel, stainless steel, non-ferrous metals, brass, aluminum, diecast or ABS plastic are suitable as base materials.
In the process of galvanizing, one or more extremely thin layers of only a few µm (1/1000 mm) are deposited onto the base material in the so-called galvanic cell.
The product to be coated is immersed into a metal salt solution (electrolytes) and connected with the negative pole (cathode) of a direct current source. The metal that is to be deposited also enters the conductive bath in the form of anodes (+) and as salt split into ions. Under current conduction, the metal ion to be deposited goes into solution and is activated by the cathode, which represents the part, and deposited there as a metal coating.
There are specific layer sequences and processing procedures, depending on the initial material to be finished (See also Copper|Nickel|Chrome) and the desired end quality.
This is where care and specific know-how come into play, – all the way up to company secrets. The evidence of sustainable quality quickly separates the “wheat from the chaff” of competitors.
