Brief Specialist Information
For the designer in mechanical engineering and precision mechanics, but also for the interested professional buyer, knowledge of the physical relations involved in galvanization is of great use. Fig. 1: Setup of a Galvanic Zinc-Bath1. Cathode conne…

Electrogalvanizing of rack objects
For all kinds of machine components and technical items electrogalvanizing with varied chromating is still the most frequently-employed protection against corrosion. This process is particularly indispensable where lacquer and powder coating would cl…

Zinc / iron alloy plating
Galvanic zinc alloy plating has for years been established as a high-quality corrosion-control measure for iron and steel products. In the salt spray test a zinc/iron alloy is distinguished by 4-5 times higher endurance until the onset of coating cor…

Electrogalvanizing of loose bulk goods
Articles of this kind (e.g. screws, nuts, bolts, smaller stampings etc.) are usually processed in rotating barrel electroplating machines (s. fig.). Here, depending on the utilisation, the most diverse metals and alloys can be deposited. Of the many…

Pearl-brightness chromium plating
The term is misleading because to be technically correct this process involves nickel plating with pearl-brightness (satin finish) and subsequent chromium plating. Items treated in this way acquire a very attractive appearance, whereby to a large ext…

High-gloss chromium plating
To be technically correct, this process – as is the case with pearl-brightness chromium plating – involves high-gloss nickel plating and subsequent chromium plating. A typical layer structure here also consists, depending on the requirement, of appro…

High-gloss and semi-gloss nickel plating
For many technical items one of the two above types of nickel plating is preferential to chromium plating for one or more of the following reasons: In particular in parts with a complicated shape, chromium plating, which does not disperse as well, of…

Galvanic tin-plating
Tin is a silvery white, lustrous metal, whose shine does not become dulled, even during storage. It is highly resistant to atmospheric influences. With the exception of nitric acid, there are hardly any dilute inorganic and organic acids that attack…
