Research Area: Plasma Coating and Sputtering

We en­coun­ter func­tio­nal coa­tings which im­pro­ve ma­te­ri­al's pro­per­ties al­most ever­yw­he­re in ouer ever­y­day life. They vary from per­mea­ti­on bar­ri­er coa­tings to scratch and wear re­sis­tant lay­ers for ma­chi­ning pur­po­ses. Coa­ting func­tio­na­li­ties ob­tain pro­per­ties such as spe­cial re­flec­tivi­ty and wetta­bi­li­ty. Many of these thin films on nanometer scale are produced by different plasma deposition techniques such as plasma enhanced chemical vapor deposition (PECVD) or physical vapor deposition (PVD). Our research activities in this broad field focus on the following topics:

  • Quartz-like SiOx barrier coatings on PET foils and inside bottles. Gas permeation is reduced to improve the shelf life of beverages.
  • Hard and wear resistant layers on mechanical tools improve their durability and therefore lower the costs and down time of machines.
  • Ferromagnetic films, which form the basis for magnetic random access memory (MRAM), which are developed for up-to-date microelectronics.
