Systems and prototypes with atmospheric pressure plasmas

Cold atmospheric pressure plasmas make many new applications possible in surface technology. The Application Center for Plasma and Photonics of the Fraunhofer Institute for Surface Engineering and Thin Films IST designs and manufactures plasma modules and individual systems.

The plasma technology used is based on the physical principle of energy supply in gases, which results in a so-called ionization: the ‘gaseous’ physical state is transformed into the higher-energy ‘plasma state’. Due to the non-thermal character of dielectric barrier discharge (30 – 50 °C) and to components for plasma generation being customizable, a wide range of different substrates such as metals, ceramics, glass, thermally highly-sensitive materials such as paper, glass fiber-reinforced plastic GFRP, carbon-fiber-reinforced plastic CFRP or plastics (polyamides, polystyrenes, etc.) can be treated efficiently and gently.

Small Particles of Great Importance

Micro-particles – they are small, barely discernible to the naked eye, and yet play a major role in the technology developed in the Application Center for Plasma and Photonics of the Fraunhofer IST. In what is known as cold plasma spraying, these particles are melted with the help of plasma and sprayed onto the plastic substrate. The benefit: Unlike other methods, wet chemical processes and therefore also environmentally critical binders and solvents are not required.

For melting the micro-particles have to enter what is called the plasma jet. Good flowability is tremendously important here since excessive cohesion of the particles would make subsequent processing much more difficult or impossible. The better the particles are separated from each other, the better they can be sprayed onto a substrate in the next step. Another advantage of using especially small particles is that high-melting materials are easier to process since the particles melt much faster. This means the entire coating process can run at comparably lower temperatures. The fast and structured coating of heat-sensitive materials such as plastics, thin glass, paper, or textiles as well as three-dimensional objects is also possible as a result.

Additionally the range of possible base materials is highly varied as well. Metals, metal oxides, or plastics can be used among others, for example to produce PCB tracks that are going to play an important role in the MID (molded interconnect devices) technology sector in the future.

About us

Company details

As an innovative R&D partner the Fraunhofer Institute for Surface Engineering and Thin Films IST offers complete solutions in surface engineering which are developed in cooperation with customers from industry and research. The IST’s “product” is the surface, optimized by modification, patterning, and/or coating for applications in the business units mechanical engineering, tools and automotive technology, aerospace, energy and electronics, optics, and also life science and ecology.  

The principle technology units at the IST are atmospheric pressure processes with the main focus on electrochemical processes and atmospheric pressure plasmas processes, low pressure plasma processes with the main focus on magnetron sputtering and highly ionized plasmas and PECVD as well as chemical vapor deposition with the main focus on hot-wire CVD. The center of tribological coatings focusses on the friction reduction, wear and corrosion protection. The Application Center for Plasma and Photonics deals with mobile plasma sources and laser plasma hybrid processes.

The IST’s expertise lies in the ability to control all of the above-mentioned processes and their combination with a great variety of thin films. Extensive experience with thin-film deposition and film applications is complemented by excellent capabilities in surface analysis using the very latest equipment and in simulating vacuum-based processes.

Choosing the optimum combination of process and coating for a particular task is one of the major strengths of the Fraunhofer IST. For an efficient technology transfer the IST offers a broad range of services, from development of prototypes and economical product scenarios to upscaling and even implementation of the technology at the customer.
