| Abstract Scope |
Polyether Ether Ketone (PEEK) is increasingly recognized for its potential in advanced coatings due to its high temperature stability and mechanical resilience. However, optimizing its performance for demanding applications remains a challenge. In this work, we demonstrate a scalable approach to enhancing PEEK coatings by incorporating Boron Nitride Nanoplatelets (BNNPs) through a solvent blending technique, followed by high-pressure cold spray deposition. The coatings were deposited on PEEK substrates and comprehensively characterized. Microstructural and spectroscopic analyses revealed strong interfacial bonding between the polymer matrix and the nanofillers. Mechanical and thermal evaluations further confirmed the synergistic effect of BNNP reinforcement, leading to a marked improvement in coating performance, including a 243% increase in hardness, a 11% increase in melting point, and an 18% increase in decomposition temperature. This study highlights the promise of cold-sprayed PEEK/BNNP composites as multifunctional coatings for aerospace, automotive, and other high-performance sectors requiring durability under extreme operating conditions. |
