Electrolytic activation

Limitations: Maximum workpiece size of 1000x1000x800mm.


Electrolytic activation can be carried out in anodic or cathodic mode, as well as based on acid or alkaline solutions. Cathodic activation is more efficient than anodic activation. However, cathodic activation also generates more hydrogen, requiring the workpiece to be hydrogen-deembrittled.


We have the capability to perform anodic activation of the workpieces in an alkaline solution. With this type of activation, the surface is minimally or not attacked at all, and only a small amount of hydrogen is generated. The activation process is conducted at room temperature.


  • Geometry of the workpiece (drawing with surface dimensions). 
  • Coating thickness. 
  • Coated area. 
  • Material.


  • Parts that are inaccessible with blasting media (e.g., gun barrels) can be activated.


Electrolytic activation can be applied to all metallic materials except magnesium, titanium, and aluminum. 

The delivered parts should be in a condition suitable for coating: 

No other layer should be applied. 

  • The surfaces should be free from cracks, pores, scratches, chips, rust, paint, wax, and the like. 
  • Construction: Sharp edges should be avoided if possible (facets, radii).
