A German research institution with a focus on energy related technologies is working on surface modification using ultrashort pulse lasers. Partners interested in functionalised surfaces for any application and materials are welcome to test the technology.
Cooperation plus value:
An ultrashort pulse laser process modifies the structure of different surfaces. New material properties can be implemented, depending on the laser parameters. Properties such as
- structure depth, roughness
- the chemical composition
- heat and fluid transfer
can be controled.
Any material including
- metals (steel, aluminium, copper, nickel)
- polymers (e.g. acrylic glass)
In a current application metal surfaces are modified in the nano and micro structure using femtosecond laser ablation. Those mechanical stable and larger surfaces are especially interesting for the usage as electrocatalyst. During the laser process, elements from the process environment can be incorporated. For example, Nickel and Copper electrodes can be alloyed on the surface with further catalytic active elements from the process ambient.
In this manner, iron alloyed nickel electrodes features an increased electrochemival activity in the alkali water electrolysis. An alloyed copper electrode features an increased activity during the electrochemical reduction of carbon dioxide. This innovative method can also be transfered to other catalytic surface reactions on various substrate matrices. With this technique, a very low amount of precious catalyst elements is used.
