Modification of mechanical, electrical, thermal, chemical, optical, haptic, biological and other properties of light metals on an industrial scale.
Surface as a micro-composite material
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:
- Plasma-chemical reaction
- 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.
Basically, there are several possible approaches that allow you to produce countless variants of the METAKER® surface with different application potentials:
1. Modification of the base material
The initial modification of the base material is the basis for each series process. The combination of standard electrolytes with application specific I/U-characteristics is designed for the industrial fabrication of microcomposites of all possible amorphous and crystalline forms of oxides, hydroxides and salts of the base material. For aluminum it is the alumina, mullite, glass, corundum, sapphire, ruby and other.
This approach offers short-term industrial implementation of new potential.
2. Modification of the base material with simultaneous integration and modification of foreign materials
The standard electrolytes can be modified by the addition of various foreign materials. Both the electrolytes and the I / U characteristics must be adapted to the specific application in this case. The foreign materials can either be integrated into the surface in their original form or in a plasma-chemically altered form.
This approach enormously extends the possible (multi) functionality. The first applications have already been successfully mass-produced, many more can be developed on request in the medium term.
3. Multi-stage or combined modification
The abovementioned processes are applied in multiple stages or combined with one another and / or with the other technologies, such as eg EPD, PVD, Sol-gel, digital printing, painting etc.
This approach extends the application potential in dimensions that are difficult to estimate today and forms the basis for future, application-specific research and advanced development.
4. Special modification
In special cases, the electrolytes, the I / U characteristics, the control technology and the system technology can be completely redeveloped.
Alloys of light metals aluminum, titanium and magnesium, regardless of their nature, can be modified:
- solid material
- open-pored metal foams
- Water-resistant industrial fabric hybrid with a light metal component
METAKER® process has several unique selling points:
- own process control with coordinated electrolytes
- economy of industrial applications (new industry standard)
- multifunctionality and structure of the boundary layers
- very sophisticated look and feel
- applications on large areas
- applications on thin sheets, films and thin films
- applications on metal mesh, metal foams, porous metals
Process steps / process temperature:
1. Degrease / 60°C - 80°C
2. Rinse with water / 10°C - 20°C
3. Modify / 20°C - 40°C
4. Rinse with water / 40°C - 60°C
5. Rinse with water / 10°C - 20°C
6. Drying / 60°C - 80°C
METAKER® Surface technology can be adapted to any system technology from the wet chemical sector. Process control allows remote monitoring and technology updates and is suitable for digital cloud business models.
METAKER® Surface is probably the most environmentally friendly surface technology on the market. There are no pollutants or hazardous substances used.
