[intro]Technical know-how is a key factor to ensure your business’ competitiveness and COATING PLASMA INDUSTRIE with its 20 years’ experience in the field of cold plasma surface treatment can help you get the knowledge you need to achieve this goal.[/intro]
In the month of February, you can attend a professional training course at CPI’s facilities in Peynier, France.
The courses are designed to:
– Provide a better understanding of cold plasma techniques
– Understand the added value the cold plasma technology can bring to your products,
– Explore the surface modifications of the processed materials, and the extensive areas of application.
Examples of topics that we will discuss during the course:
– Definition and characteristics of plasma
– Plasma parameters (pressure, flow, power, duration)
– Interactions plasma – surface
– Reactive species in plasma
– Reactions in the surface (cleaning, etching, activation, grafting, deposit-linked)
– Plasma and adhesion
– Optimization and characterization of treatment
– Evolution of the treatment over time
If you wish to participate in the course, please contact [email protected]
to get information on availability and pricing.
