QUALITATIVE ANALYSIS OF COMPOSITE ZN-PTFE COATINGS

Abstract

The aim of this work is to obtain completely new technology of surface treatment. Studies and research in the area of deposition showed that lubricant composite coatings based on zinc with PTFE (polytetrafluoroethylene) particles offer unexpected possibilities of electrodeposition and innovative approach to surface protection. Integral part of this research is a characterisation of applied coatings and it requires the development of reliable methods to determine the coatings ́ composition, PTFE content and distribution in the composite coatings. A number of analytical methods were used to characterise all required parameters. Optical microscopy, infrared spectroscopy, Raman spectroscopy, and optical emission spectroscopy were used for characterisation of prepared coatings. Each method proved better or lesser ability to describe tested coating. It is possible to say, that IR spectroscopy allows an easy qualitative analysis of the coatings.
