Zinc plating and passivation
To ensure a high level of corrosion resistance for metal items, while achieving maximum adhesion of chromating, one of the most used treatments is certainly the zinc-nickel treatment. Applied in compliance with current regulations, it is one of the services most requested from Zincoplating, particularly from clients in the automotive sector. Following the treatment, it is possible to perform passivation in various colours depending on requirements.You can then get a finished product iridescent gray or black. To further increase the resistance to corrosive agents, a sealant is applied to the product, again using immersion. Increasingly requested, especially in the car industry, the finishing in black chromic conversion is carried out with the use of a solution of chromium III, chromium VI and silver salts. Thanks to the new technologies now available, it can be carried out even without the use of expensive salts, with a consequent reduction of costs.
