Deposition of polytetrafluoroethylene coatings by means of the innovative PED technique DOI:10.15199/28.2019.5.3

  1. INTRODUCTION The progress in the field of electronics is determined by the receipt of new materials with special properties and the development of the technology of their application. One of these modern coating techniques is Pulsation Ablation with an Electron Beam (PED). The PED application is an innovative technique that can be used to produce high-quality, thin coatings. This process has many advantages, including relatively low operating costs, the possibility of controlling the stoichiometry of the material applied, and the possibility of applying material coatings transparent to the laser beam. Over the last few years, polymer-based materials have become increasingly important in science and technology. There is a growing interest in polymeric materials applied in the form of thin coatings based on advanced energy sources, which can provide an interesting alternative for obtaining coating materials with new properties [1]. At present, the application of thin polymeric coatings using Electron Beam Pulse Ablation method is a very little known technique. So the knowledge on this topic available in literature is very limited. The purpose of this study is to provide an insight into the PED process and to provide a source of scientific information based on the literature on the subject, as well as own research. The scope of the experiments includes: production of polytetrafluoroethylene coatings on silicate surfaces by Electron Pulse Ablation method: -- conducting a study determining the chemical structure by FTIR (Fourier Transform Infrared Spectroscopy) spectroscopy, -- examination of the thickness of the produced coatings and then measurement of their adhesion, -- determination of the influence of selected parameters of the method on the rate of coating deposition using various voltages, -- determination of the influence of basic parameters of deposition on the morphology of coatings. 2.
