Which can be categorized as a use of plasma in technology?

The use of plasma is in technology is very broad, including the medical sector, automotive and areas of scientific development

Explanation:

Plasma technology can be used in various ways, where it is a matter of joining materials or modifying the surface properties in a defined way. This technology can modify the surfaces treated, the cleaning of contaminated components, the activation of plastic parts, the etching of fluoroplastics and silicon and the application of coatings to these plastic parts are some applications.

 Plasma systems are used in the following industries, among others: Electronic industry and semiconductor manufacturing: plasma cleaning to degrease metal surfaces before welding, printing circuits or coating and for the extraction of undesirable materials or the addition of others.    Medical technology: Cleaning and sterilization with plasma implants.  Rubber processors: Elimination of lubricants before sticking or joining chemically Automotive technology: Plasma cleaning applied at numerous stages along the production line allows combinations of materials that are only possible with the help of plasma procedures.  Electron Microscopy: the plasma is used to clean the microscope nozzles, grids and sample holders.
