Passivation

Thick Layer Passivation

Thick layer passivation is the most widely used type of passivation of zinc-nickel. It has a bright grey color with a slightly purple tinge.

Black Passivation

This kind of passivation is very popular for its premium appearance of beautifully rich black color and higher corrosion resistance. Zinc-nickel is harder than typical fine zinc; therefore, these parts tolerate the grinding process in barrel lines better.

Sealing Coats

The purpose of sealing coats consists in achieving the required friction factor. The coat also prolongs the corrosion resistance of the part.

CAUTION! Most sealing coats cannot withstand heating. That is why they are not suitable, for example, for subsequent powder coating.

Barrel Line for Zinc-Nickel
and Pure Zinc

NEW TECHNOLOGY 2019

A combined line for zinc-nickel alloy and fine zinc with an automatic painting line built in 2019.

Annual throughput:
Zinc-nickel 4,000 tons
Pure zinc 3,000 tons

Automatic process for sealing coats.

Ensuring the constancy of process quality thanks to a computer-controlled program.

Secured process.

Extended options to set process parameters.

Special barrels for parts with sharp tips.

Plating layers are checked using non-destructive measurement with an X-RAY device.

Data archiving, process history and traceability.

Certificate-guaranteed quality.

Inspection of the Process Correctness

The plating quality inspection shall be carried out with measuring tests using three pieces from each barrel or rack. The measurement is carried out using a non-destructive method with the X-RAY device. Moreover, our operators check the plating visually (in particular, they focus on the integrity and color of parts).  

The correctness of plating (in particular, the integrity and color) is also visually checked by our operators.

Certificates, Certificates of Conformity

The certificate of conformity is issued on the basis of measured values which are stored in the internal system. The certificate guaranteeing conformity shall be drawn up upon the customer’s request for each article of goods and delivery separately. The certificates are available for downloading in the client zone.

De-embrittlement

The hydrogen bake out cycle of parts consists in heat treatment at around 200 °C for 2 to 24 hours, depending on material hardness. The hydrogen bake out cycle must begin immediately after galvanizing. Through the hydrogen bake out cycle, the parts made of harder materials (over 1,000 Rm) are protected against the risk of hydrogen charging and hydrogen embrittlement of the matrix, of which they are made.

Corrosion-Resistance Testing

The tests of the prescribed corrosion resistance for galvanized parts and parts with zinc-nickel treatment are carried out internally in our laboratory, using salt spray tests.  The salt spray tests conform to “automotive” standards, and their output is always a report indicating the result.

The internal tests of corrosion resistance also help us check the correct process settings.  The corrosion-resistance tests are also offered as a separate service.  

Common standards, based on which the neutral salt spray (NSS) tests are performed: DIN 9227, ASTM B117,...
