Modification of mechanical, chemical, electrical, optical, haptic, biological, ecological and technological properties of light metals.



METAKER® Surface is a process for the electrochemical- chemical modification of light metal surfaces during the dipping process. Under influence of a million micro-arcs, the micro-contracture of a workpiece in the surface layer area is transformed into a multifunctional, micro-constructed and activated gradient material. The transformation process is complex and consists of a dynamic symbiosis of several single processes such as:

  • Thermolysis
  • Plasma-chemical reaction
  • Cavitation
  • Heat treatment
  • And more

The resulting gradient material is a complex, heterogeneous, multifunctional mixed material of micro/nano-phases of various modifications of oxides, hydroxides, salts and optionally other materials, whose composition, structure and properties can be customized in any specific area.

For example, an application-specific, tribological surface consists of a “hill chain“ with a very large proportion of material (green marking in the picture below), intervening  “valleys“ (yellow marking) and homogeneously distributed “caves“ or pores with a complex spatial structure (red marking). The micro hardness is in the range of 334 HV to 1169 HV.

The chemical, mechanical, and topological features of the surface can be tuned specifically for different applications in particular settings, and unlike other surface technologies, have many benefits in different functions.

  • Wear resistant
  • Cyclic loading
  • Temperature resistant
  • Corrosion resistant
  • Dielectric
  • Electrically conductive
  • Thermal conductive
  • Heat insulating
  • Light absorbent
  • Light reflecting
  • Catalically active
  • Impregnatable
  • High quality decorative
  • Bioactive
  • And much more


Further enormous potentials can be achieved by a multiple coupling of different METAKER® processes , as well as by a combining other processes such as impregnation, PVD, Sol gel, KTL, digital printing and more.


METAKER® process has several unique selling points:

  • Own process control with coordinated electrolyte
  • Economy of industrial application (new industry standard)
  • Multifunctionality and structure of the surface layer
  • Very sophisticated look and feel
  • Application on large areas
  • Application on thin sheet or films
  • Application on metal mesh, metal foams and porous metals
  • And more

Work Piece

Alloys of light metals such as aluminum, titanium, magnesium etc. can be treated. Currently we offer applications exclusively for aluminum alloys. The development of application for magnesium and titanium is also possible on request.


System Engineering

METAKER® Surface Technology is system-independent and can be adapted to any system technology from the wet chemical sector.

Process control allows remote monitoring and technology updates and is suitable for a digital cloud business models.

Environmentally Friendly

METAKER® Surface is probably the most environmentally friendly surface technology currently on the market.
