Electroplating

 

zincare electroliticaRelatively low cost, protective nature and attractive appearance of electroplating are some aspects that make its use to be so prevalent, from screws to washers and nuts to automotive parts, components for industrial applications etc.
Coatings obtained by electrodeposition have a smoother and more lustrous look and the dimensional accuracy of parts obtained is very high, which is very important especially for threaded components.
Semi-automatic installation of Betak S. A. enables the following types of depositions:
•    Weakly acid electroplating
•    Alkaline electroplating
•    Zn - Ni deposition
•    Nanometric co-deposition - Betak Technology
•    Trivalent chromium passivation

 

Tank sizes: 1.7x1.2x1.1 m
Maximum weight of product: 300 kg
Production Standards: DIN 50961, SR EN ISO 2081, STAS 2700/8
Zinc layer thickness: 5 - 25 µm
Certifications: TUV (Quality, Environment, Occupational Health), AFER, ELECTRICA, ICECON

Basically, the design for electroplating must allow free and easy access of surface preparation solutions and deposition electrolyte on all surfaces, and sharp corners and blind holes should be avoided. The pieces must be provided with noncritical areas and preferably hidden for mounting on brackets.

 

Electroplating - Benefits

Coatings obtained by electrodeposition have a smoother and more shiny look, and the dimensional accuracy of the components obtained is very high, which is very important especially for threaded components. The coating thickness can be rigorously controlled. The lifespan of coatings obtained is directly related to the type of coating and type of passivation applied.

  • Reduced cost;
  • Protection against corrosion even in the condition of slight damage to the surface coating;
  • Pleasant aesthetic appearance;
  • Excellent adherence and ductility;
  • Even distribution of the film thickness;
  • Batch processing;
  • Reduced stresses in the coating;
  • Processing takes place at ambient temperature (the possibility to process components which cannot withstand the processing conditions of other methods of corrosion protection).

Electroplating process

 

zincare electrolitica  

Semi-automatic installation of Betak S. A. enables the following types of depositions:

  • Weakly acid electroplating
  • Alkaline electroplating
  • Zn - Ni deposition
  • Nanometers co-deposition - Betak Technology
  • Trivalent chromium passivation

Electrolytic galvanizing process includes several phases:

 

Chemical degreasing

Surface treatments begin by chemical degreasing that is designed to remove both fat and fine dust and the thermal treatment salts from the surface of the part.

 

Pickling

Pickling is the elimination of corrosion products from metal surfaces.

 

Electrochemical degreasing

The electrochemical degreasing completes the chemical degreasing to remove the residual film of fat bodies and discard the surface of all impurities.

 

Activation

It removes the thin film formed during transfer by acid washing.

 

Actual electrolytic deposition

A thin and uniform electrolytic zinc layer is deposited on the surface of the parts.

 

Passivation

Passivation has the role of forming a film of compounds that prevent reactions which may occur on the zinc surface with the environment and to provide corrosion resistance and a nice appearance of the piece.

 

Washing

The washing phase takes place after each stage of the technological process to remove the solution film adhering to the surface of the piece.

 

Drying

Drying takes place in a room type furnace.

Electroplating - Prescription

Maximum weight of bath dipped benchmark: 300 kg

Zinc coating thickness: 5 - 25 µm

Certifications: TUV (Quality, Environment, Occupational Health), AFER, ELECTRICA, ICECON

Basically, the design for electroplating must allow free and easy access of surface preparation solutions and electrolyte deposition on all surfaces, and sharp corners and blind holes should be avoided.
