M-21: Cold Spray Deposition onto CFRP with Engineered Bond Layer: Po-Lun Feng1; 1University of Southern California
Cold spray is a solid-state powder deposition process in which particles are accelerated via a supersonic gas flow to impinge on and deposit onto substrates. Cold spray metal onto metal have been widely studied, but few studies have been devoted to deposition of metal onto polymer composites. One of the main problems reported is the erosion of fiber and thermoset substrates. To avoid erosion of the carbon fiber reinforced polymer (CFRP) and achieve cold-weld of impinging particles, a bond layer (BL) is required. There is a need to engineer a bond layer compatible with cold spray and develop understanding of the quantitative effects of bond layer microstructure on coating adhesion. Adhesion of cold-sprayed coating is determined by the BL-CFRP, particle-BL and particle-particle bonding. Interface engineering of the bond layer microstructure can enable hybrid process routes to impart metal-like durability on composites for light-weighting of metallic components and facilitating rapid repair.
M-23: Numerical Simulation Study of Strip Floater: Ning Mao1; Chengbo Wu1; Zhihui Guo1; 1Chongqing University
Aiming at the setting of the nozzle angle, nozzle width and nozzle spacing of the strip floater in a steel mill continuous withdrawal unit, a three-dimensional model was established using ANSYS software to study the pressure distribution and deformation of the strip surface under different nozzle parameters. By comparing the simulation results, the optimal nozzle setting conditions were obtained, which provided reliable reference data for the actual production of strip steel.
