Industrial Application of Plasma

One of the latest trends Aurica has been working on is research in the field of plasma surface treatment. Industrial use of plasma is a quickly developing and promising area of scientific and technical studies. Plasma is “the fourth state of matter”, ionized gas obtained by means of letting gas go through an electric discharge. Passing into the state of plasma, matter acquires a new ability to influence materials it contacts. The actual properties of plasma vary depending on a number of parameters (the type of gas, the frequency of excitation source, the duration of treatment etc.). These properties predetermine the areas of its application. Plasma can be used to treat various materials, without any considerable limitations.

Plasma can affect surfaces in a number of ways. First, ion bombardment removes the upper layer of the surface. Second, ionized gas enters into a reaction with the surface of the material. Third, released particles of plasma emit UV-radiation that breaks molecular chains of carbonic compounds. The enumerated effects of plasma can be used for the following purposes:

  • Surface cleaning
  • Surface activation
  • Surface etching
  • Coating

Today experts at Aurica offer the following services in the sphere of plasma technologies:

  • research work concerning industrial application of plasma;
  • free treatment of experimental specimens;
  • plasma treatment of customer’s materials.

Cleaning

Ion bombardment cleans surfaces physically (sputtering) and, depending on the gas, also chemically. The contamination is vaporized and sucked away. Applications of plasma cleaning: Removing grease, oil, oxides or silicone Pre-treatment and preparation for bonding, soldering or gluing Pre-treatment for finishing metals Applications: Removal of

Activation

Plasma treatment of a plastic surface with e.g. oxygen. Radicals are being formed which lead to a good adhesion of finish and glue. Applications of plasma activation: Pre-treatment of plastics for gluing Pre-treatment of plastics for finishing Treatment before printing Applications: Adhesion pretreatment for plastic
