Characteristics

The range of possible surface properties and their combinations that can be achieved on light metals is so great that it cannot all be mentioned here. In addition, the same property can be used very differently depending on the application.

Below you will find general information about selected properties. The information relevant to your application is available upon request.

 

 

Outer layers

Full-surface, homogeneous or partial, deliberately inhomogeneous modification of surface layers in the range of 2 to 200 μm.

 

Ductility

Under certain conditions, the layers with very good ductility for e.g. Cylinder tracks are developed in internal combustion engines. Modified sheets, aluminum fabrics or films can be e.g. bend radii thicker than a wall.

 

Micro hardness

Micro hardness is heterogeneous and can have a hardness gradient of 100 to 2,200 HV. It is always determined by using several measurements.

 

Chemical resistance

Due to the adjustable chemical composition or combination with other methods, the surfaces can be adjusted to an extreme chemical resistance.

 

Heat resistance

The working temperatures of the surface are limited by the melting temperature of the substrate. For a short time, thermal shocks of up to 1,000 ° C - 2,000 ° C can be sustained.

 

Thermal conductivity

Depending on the application, the surfaces can be made to have very good thermal conductivity (e.g., cylinder liners or electronics) or to be thermally insulating (e.g., heavily used tribological applications).

 

(Di) Electrical properties

The layers can be designed both as electrically conductive and electrically insulating.

 

Homogeneity

The coating is very even. The most complex shapes with corners, sharp edges, channels, reliefs, blind holes, etc. can be modified very homogeneously.v

 

Impregnation / porosity

Both the porosity of the surfaces and the pore sizes can be varied within a certain range. Excellent absorbency and atomic adhesion to the substrate make the thin layers a better alternative to anodized adhesive substrates for subsequent painting or bonding.

 

Light absorption / Light reflection

A light absorption of up to 94% allows use in high-quality optics and electronics. A light reflection of up to 80%, extreme heat resistance and thermal conductivity bring advantages for modern lighting systems.

 

Aluminum thin films

The thin aluminum layers deposited in a thin film on different substrates (e.g., steel) can be modified.

 

Hybrid materials

Alloy components in water-resistant hybrid materials (e.g., aluminum over-molded with plastic) can be modified.

 

Decorative properties

Matt, non-reflecting, optically demanding, durable, chemically resistant, colored surfaces are ideally suited for decorative applications.

 

Mechanical machining

The surfaces can be mechanically processed conventionally. The modified workpiece areas, which had to be changed as part of a change process, can be modified later as well.

 

Stiffening

For certain ratios of shapes, alloy, and layer type and layer thickness, of the modified surfaces can be used to stiffen thin-walled structures.

 

Other features

You will learn about other interesting but easily understandable properties in a personal conversation.
