Lire la suite >Nanoceramic interlayers at the polymer-polymer interfaces have been demonstrated to be extremely vital for the coating buildup (up to 4 mm thickness) during cold-spray consolidation of Ultra-High Molecular Weight Polyethylene (UHMWPE). This paper investigates the polymer-polymer interface formation and strength as a function of the compressive state of the consolidation and the influence of the interlayers at the bonding interface. The research study suggested that the polymer-polymer interfaces get reinforced at high compressive consolidation by two in-situ mechanisms: (i) formation of core-shell surface composites; (ii) formation of a network of polymer-nanoceramic-polymer knots during the polymer chain inter-diffusion. On the other hand, a low compressive consolidation fails to create the surface compositing and polymer-nanoceramic-polymer links at the polymer-polymer interface yielding a weaker interface strength compared to that of a polymer-polymer interface. The nanoceramic particles in the interlayer, in this case, acted as a defect preventing efficient wetting and subsequent inter-diffusion between adjacent polymer particles.Lire moins >
