In this paper, solution precursor plasma spraying (SPPS) was employed to prepare a porous YSZ/LSM composite cathode for solid oxide fuel cell (SOFC). The surface morphology and microstructure of the deposits were characterized using SEM. effect annealing treatment on SPPS examined. results showed that as-sprayed presented aggregate with size range 10–60 μm when alcohol used as solvent distance ...

Abstract In plasma spraying, compared to other thermal spraying process variants, only a small part of the available energy is used build up coating. Another peculiarity this relatively strong oxidation sprayed metallic particles, caused by high temperatures and turbulent flow jet in combination with ambient air. A promising solution for increasing efficiency solid shroud that surrounds thus pr...

Thermal barrier coatings were prepared on magnesium alloy substrate by plasma spraying, and thermal shock test, test arc wind tunnel carried out. The failure mode, microstructure phase transition of coating after analyzed SEM XRD change temperature rise rate during is means measurement. analysis results show that the structure sprayed surface consistent before shock, no occurs spraying shock. m...

Indoor residual spraying—spraying insecticide inside houses to kill mosquitoes—is an important method for controlling malaria vectors in sub-Saharan Africa. We propose a mathematical model for both regular and non-fixed spraying, using impulsive differential equations. First, we determine the stability properties of the nonimpulsive system. Next, we derive minimal effective spraying intervals a...
