讲座介绍:
Thermal spraying is a melt spray deposition process, in which particles in the diameter range of 1-100 microns are heated, melted, propelled and impacted onto a prepared substrate. A rapid sequence of events occurs: melting, spreading and rapid solidification, all taking place in microsecond timescales, enabling materials synthesis from extreme conditions. Coating is resultant from successive assemblage of microscale impacted droplets producing mesoscale thick films. Resultant deposits are defected, anisotropic, layered structures with concomitant implications on properties. The layered assembly also imparts gradients in through thickness residual stresses. These effects are in large part deemed “unintentional” and incorporated in many applications with limited manipulation. With advancements in understanding of process dynamics and the ability to control microstructures, a fresh opportunity is available to engineer and properties and functionalities through optimization of layered assembly. In this presentation, embodiments of such concepts will be shown using the interplay among coating architecture design, materials and manufacturing. Specific examples include novel multifunctional thermal barrier coatings, multifunctional coatings in fuel cells and thermoelectric devices. Illustrative examples of their applicability in industrial systems will also be highlighted.
