Plasma Knowledge Base

An ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge.

Plasma surface activation is the process by which surface polymer functional groups are replaced with different atoms from ions in a plasma.

Using plasma to clean materials before processing them.

Plasma coating is basically the spraying of molten or heat softened material onto a surface to provide a coating.

Plasma etching involves a high-speed stream of glow discharge (plasma) of an appropriate gas mixture being shot (in pulses) at a sample.

Surface energy is the excess energy at the surface of a material compared to the bulk, or it is the work required to build an area of a surface.

A surface treatment is a process applied to the surface of a material to make it better in some way.
