Polyetheretherketone (PEEK) Coatings on Stainless Steel by Electrophoretic Deposition

Abstract

Polyetheretherketone (PEEK) particles were deposited on 316L stainless steel substrates by electrophoretic deposition (EPD) from ethanol suspensions producing uniform coatings. The process involved deposition of two layers and subsequent densification of the coating by sintering at 343 °C for 30 minutes. The microstructure and thickness of the coatings were reproducible demonstrating the convenience of EPD as a low-cost method to produce homogeneous PEEK films on metallic substrates.
