Abstract

Fluoropolymer and other polymer materials are extremely difficult to coat with using solid state deposition technique such as cold spray (CS). Generally, the polymer deposition using CS is characterized by a relatively low deposition efficiency (DE) compared to metal. In this article, the study of Fluoroethylene Propylene (FEP), a perfluorinated polymer particle's solid-state deposition using cold spray has been studied. The study incorporated parameters related to CS process, including powder size, cold spray gas temperature, gas pressure and substrate surface treatments. In addition, powder modification technique using fumed nano-ceramic particles as additive to the feedstock has been studied as well. The results show a number of parameters affected the DE; particle size, traverse speed, gas temperature, and addition of fumed nano-ceramic, indicated a better DE. Moreover, FEP coating produced in this manner, retained the hydrophobic property.
