Market specific certifications
Passivations and chromatings are very popular in the electronics industry because of the low surface resistance. They are used in the aerospace industry because of their excellent corrosion protection and serve as ideal adhesion primers for paints.
BWB meets the uncompromising quality requirements of the aerospace industry when chromating aluminium, as confirmed by the EN 9100 and Nadcap certifications.
Passivation of steels
Passivation of steels after prior galvanising refers to the process of treating galvanized steel to further improve its corrosion resistance. This is done by forming a thin, protective passive layer on the surface of the galvanised steel. This passive layer protects the zinc layer from corrosion (white rust) and thus improves durability.
Passivation of stainless steel
Passivation of stainless steel is a chemical process that creates a thin and protective layer on the surface of the metal. Passivation is an important step in the manufacturing of stainless steel products to increase their durability and resistance to corrosive environments.
Passivation of magnesium
Das Passivieren von Magnesium ist ein Verfahren, bei dem die Oberfläche des Metalls chemisch behandelt wird, um eine schützende Schicht zu erzeugen. Diese Schicht erhöht die Korrosionsbeständigkeit des Magnesiums und verbessert seine Haltbarkeit in anspruchsvollen Umgebungen. Wir bieten das Passivieren von Magnesium mit dem bewährten Verfahren SurTec 650 an, das eine effektive und umweltfreundliche Lösung für den Korrosionsschutz darstellt.
