What is plasma? ?
When a substance receives a continuous supply of energy, its temperature rises, causing it to change from a Solid state to a Liquid state, then to a Gas state.
If energy continues to be supplied, the atoms lose their electrons, forming a mixture of charged particles – negative electrons and ions. This phenomenon gives rise to Plasma, also known as the fourth state of matter.
Why is this interesting?
- The species present in the plasma react with each other and with nearby surfaces.
These reactions cause physicochemical changes to the surface and result in new characteristics.
- Adaptable to a wide variety of materials and geometries, the treatments induce localised and lasting changes.
- The processes do not use solvents and consume little energy, making it a clean and sustainable technology.
