Usually Openair® plasma systems are supplied with compressed air as the assist gas. However, if an oxide layer is to be removed from surfaces, the assist gas is simply replaced with a mixture of gases and appropriate functional constituents. Forming gas, a mixture of nitrogen and hydrogen, is especially suitable for such plasma cleaning. The hydrogen is supplied in a non-critical, non-explosive mixture ratio (no greater than 5%).
The characteristics of the resulting forming gas plasmas differ completely from those of the usual Openair® plasma. Instead of incorporating oxygen in the surface of the material, it is securely removed by the plasma treatment. Even highly oxidized copper surfaces are bare again in a short period of time. This form of plasma cleaning leads to safe contact cleaning and therefore to reliably reproducible soldering and coating processes that are of fundamental importance for fuel cells and batteries.

Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
In addition to the Openair-Plasma Systems for surface treatment Plasmatreat GmbH also offers individual production cells with automated solutions to ensure seamless integration in the production lines. Plasma Treatment Units (PTU) are tailored to the customer's technical processes and are equipped with various operating options. Here Plasmatreat offers the solution of coordinated process automation combining efficient surface treatment and a perfectly coordinated handling of assemblies and components.
Plasmatreat plans to get more involved in the disinfection industry by providing solutions for disinfecting protective clothing during the current corona crisis.
