Plasma Driven Surface Treatment

Plasma Driven Surface Treatment

To work with materials and unleash their true potential, almost every industry needs to activate their surface to make them more reactive. The increase in the material’s reactivity makes it easier to work with and allows it to be used more effectively. Plasma is the fourth state of matter and is used in almost all industries as plasma technology is one of the most economical methods of surface treatment.

How does plasma activate surfaces?

Plasma state is achieved when additional energy is added to gaseous ions. When plasma comes into contact with the surfaces of polymers, it alters the surface by attaching functional or polar groups to it. The addition of polar or functional groups makes the materials reactive as these groups easily combine and react with other chemical groups. Once the properties of the material are altered, they can be used for a variety of different purposes.

The activation process primarily uses oxygen as a catalyst; however, some materials can react with plasma in open air, without the need of providing additional oxygen for the reaction.

What are the common types of plasma driven surface treatments?

  • Plasma surface treatments can be used for the following industrial treatments of materials:
  • Plasma Driven Surface Activation: Plasma treatments used to activate surfaces
  • Plasma Cleaning: Plasma is used to clean and prepare surfaces for various manufacturing processes
  • Plasma Coating: During plasma coating, an object is bombarded with plasma to allow a layer of polymers to form over the object.
  • Plasma Bonding: Plasma is used to lower the energy needed to bond two materials together.
  • Plasma Surface Modifications: Plasma treatments can be used to generate new properties of materials by activation, conditioning, and functionalization.
  • Plasma Ashing: Plasma ashing is the removal of carbon from products during manufacturing or cleaning processes.
  • Reactive Ion Etching: In this process, plasma treatments etch the surfaces which have already been treated.
  • Plasma Functionalization: This process improves the functions of materials, especially adhesiveness, bonding, and printing.

What makes plasma ideal for surface treatment?

An Overview of Surface Activation

Materials with low surface energies like polymers and metals are not wettable by printing ink and adhesives. These materials require some treatment to match the surface tension of adhesives. The procedure of using chemicals, plasma or radiations for increasing the surface tension of non-polar materials is called as surface activation.

Although every method of activation has its own pros and cons, choice of the treatment method depends on the nature of the material being treated. For example, plasma treatment is commonly used to activate the polymer surfaces, while for metal surfaces UV radiations are used.

Plasma Treatment in the Automotive Industry

With the boom of customization and automation in the automotive industry, the need of finely tuned methods for producing high quality automobiles is also increasing. The automotive industry relies on a number of robust preconditioning processes for producing rugged and reliable automobiles. One of such processes is plasma treatment. Although automobile manufacturers have been using plasma treatment in the automotive industry for the surface treatment of automotive parts for years, plasma treatment can also be used for enhancing bonding characteristics of automobile parts.

What is Plasma Treatment?

Plasma refers to the fourth state of matter. According to the principles of chemical reactions, an element can change its state if enough energy is provided. When an element is in the gaseous state, extremely high energy is required to change the state from gas to plasma. Plasma consists of partially ionized atoms which possess high energy. When these excited particles come in contact with a metal surface they transfer their energy to the metal atoms, thus modifying the chemical and physical properties of the material. These modifications in the chemical properties make the material suitable for painting and adhesive bonding. This is the reason that plasma treatment is one of the most commonly used preconditioning processes in the automotive and aircraft industries.

How it Increases Surface Tension?

Automobiles are made of metals and plastic and both of these materials have considerably low surface tension. Low surface tension means less probability that the printing ink or paint will stick to the material surface. Plasma treatment in the automotive industry is used to increase the surface tension of plastic and metals and make them suitable for printing, bonding and painting. Read more
