    Published 2024-10-01
    “…The thermal barrier stealth integrated coating material prepared by atmospheric plasma spraying process has important application prospects in the hot end components of aircraft engines.For studying the optimization of atmospheric plasma spraying process parameters for LaFeO3/8YSZ composite coating, a pure LaFeO3&#x00A0;coating was first prepared, and high-temperature characterization of the thermal and physical parameters of the coating was completed at 1 150 ℃.A finite element model of LaFeO3/8YSZ composite coating was established,and the influence of preparation temperature and coating thickness ratio on residual stress of the sample was analyzed in detail.Results showed that as the preparation temperature increased, the in-plane compressive stress of LaFeO3&#x00A0;and 8YSZ coatings gradually increased.The surface internal stress of LaFeO3&#x00A0;coating changed from -96 MPa at 150 ℃to -152 MPa at 250 ℃, and similarly, the surface internal stress of 8YSZ coating increased from -48 MPa to -86 MPa.Besides,the compressive stress state was beneficial for extending the service life of coatings in high-temperature service environments.Due to the thermal expansion coefficient of LaFeO3&#x00A0;being close to that of 8YSZ, the change in the thickness ratio of LaFeO3/8YSZ had little effect on the residual stress distribution of the double-layer coatings at a given total coating thickness of 1.0 mm.…”

    Influence of Surfactant on the Morphology of Copper Oxide Prepared from Acidic Etching Waste Solutions by ZHANG Tianchun, WU Daoxin, JIANG Zhengjin, XIAO Zhongliang

    Published 2024-09-01
    “…In order to study the effects of four surfactants, dodecyl dimethylamine ethylene lactone (BS-12), sodium dodecyl sulfate (SDS),cetyl pyridinium bromide (CPDB) and Tween-80, as well as their addition sequence and calcination temperature, on the morphology and particle size of copper oxide (CuO) prepared from acid etching waste solution.The microstructure of CuO was characterized using X-ray diffractometer (XRD) and infrared spectrometer (FT-IR).The micro-topography of copper oxide was examined with scanning electron microscope(SEM).The particle size distribution and thermal stability of CuO were investigated through particle size analysis and thermogravimetric (TG)testing.Molecular dynamics calculations were conducted using the Forcite module in MS software under the COMPASS force field to study the energy changes during the adsorption process of surfactant molecules on the CuO surface.Results showed that after the addition of surfactants,CuO particles exhibited uniform distribution and consistent size.The four optimal surfactants were identified as BS-12, SDS, CPDB and Tween-80.The order in which the surfactants were added did not affect the composition or morphology of the CuO product.The CuO samples prepared with BS-12 added first had a smaller average particle size compared to those with BS-12 added later, with sizes of 2.85 nm and 7.50 nm, respectively.When calcined at 400 ℃, CuO particles prepared with BS-12, SDS, CPDB and Tween-80 all exhibited irregular sheet-like structures with increased average particle sizes of 25,27,40 and 55 nm,respectively.After simulated motion,all four surfactants spontaneously adsorbed onto the CuO surface, with temperature and energy stabilizing rapidly after brief fluctuations, indicating the relative stability of the adsorption model systems.The adsorption energies of BS-12, SDS, CPDB and Tween-80 on the CuO surface were -762.73, -556.10,-619.47 and -739.81 kcal/mol, respectively, with the adsorption strength ranked as BS-12>Tween-80>CPDB>SDS.The addition of surfactants in the preparation of CuO from acidic etching waste liquids effectively improved the uniformity of CuO particles.…”
