Plasma technology has been an important production tool for many
decades in the fabrication of microelectronic devices for example. Over
this period, plasma technology has also become invaluable in many other
areas of industry and including automotive, medical devices, textiles,
and aerospace to name but a few.
Plasma treatment is used to clean and activate surfaces to improve
their adhesion characteristics. Plasma cleaning removes trace organic
contamination from the surface, which would otherwise prevent good
adhesion. At the same time, plasma treatment activates the surface and
turns it from a low to a high surface energy state so that it becomes
easily wettable by adhesives, paint, glue etc. Plasma treatment solves
problems of poor adhesion in many industries.
Plasma treatments are used to alter the surface properties of a wide
range of materials to make them easier to bond, glue and paint. By
treating parts we both clean and activate the surface, improving their
It’s useful to start by defining what a plasma is. Solid, liquid and
gas are the three states of matter we are all familiar with. We can move
between the states by adding or removing energy (e.g. heating/cooling).
If we continue to add enough energy, gas molecules will become ionised
(lose one or more electrons) and so carry a net positive charge. If
enough molecules are ionised to affect the overall electrical
characteristics of the gas the result is called a plasma. Plasmas are,
therefore, quite rightly, often referred to as the fourth state of
A plasma contains positive ions, electrons, neutral gas atoms or
molecules, UV light and also excited gas atoms and molecules, which can
carry a large amount of internal energy (plasmas glow because light is
emitted as these excited neutral particles relax to a lower energy
state). All of these components can interact with the surface during
plasma treatment. By choosing the gas mixture, power, pressure etc. we
can quite precisely tune, or specify, the effects of the plasma
