Temperature Influences on Preparation and Tribological Characteristics of Electrostatically Sprayed PTFE/PEEK Composite Coatings

Abstract

Composite coatings of PTFE/PEEK (Polytetrafluoroethylene/Polyetheretherketone) were prepared by electrostatic powder spraying method. The factors were investigated on the preheating temperature and working temperature by the orthogonal experimental method. The results show that 250°C preheating temperature and 100°C working temperature are better conditions for playing good performance of PTFE/PEEK coatings.
