As a significant parameter in tuning the structure and performance of boron-doped diamond (BDD), thickness was focused on mediation boron doping level electrochemical properties. BDD films with different thicknesses were deposited silicon wafers by hot filament chemical vapor deposition (HFCVD) method. The surface morphology composition characterized SEM Raman, respectively. It found that an increase film resulted larger grain size, reduced boundary, higher level. electrode equipped cyclic...
The YSZ coatings are prepared by the plasma spray-physical vapor deposition (PS-PVD) technology based on a specific experimental design. structure, thickness and growth angle of entire circumferential surface cylindrical sample studied. results indicated that deflection related to orientation location. numerical simulation multiphase mixed fluid near substrate is carried out regularity mechanism PS-PVD deduced. rate local characteristics flow field, directly proportional field pressure...
The deposition of photocatalytic TiO2 coatings with plasma spraying is attractive for large-scale applications due to its low cost and simplicity, but it still a challenge obtain coating high anatase content. solidification pathway inflight melted particles was investigated in the present paper, enhanced activity were obtained without significant loss microhardness. microstructure, phase composition, crystallite size by scanning electron microscopy (SEM) X-ray diffraction (XRD)....
Maintaining the geometrical stability of hot filament is a challenge in chemical vapor deposition (CVD) over larger area since deformation varies distance between and substrate and, consequently, destroys uniformity diamond deposition. Herein, Ta straightened with tensile stress ranging from 4.40 to 11 MPa suppress deformation, during CVD process film evaluated. Scanning electron microscopy energy dispersive X‐ray are further utilized investigate morphological structural evolutions filament....
In thermal plasma spraying process, anode nozzle is one of the most important components torch. Its inner contour controls characteristics arc/jet, determining motion and heating behaviors in-flight particles hence influencing coating quality. this study, effects contour, standard cylindrical nozzle, cone-shaped Laval with conical shape diverging exit (CSL nozzle) on arc voltage, net power, efficiency, jet characteristics, particle behaviors, properties have been systematically investigated...
(Mn, Co)3O4 spinel is widely used to protect the metallic interconnect of solid oxide fuel cells while it suffers deoxidization during preparation by plasma spray. This work was proposed study effect spray parameters on microstructure and conductivity coatings. In this work, coatings were prepared atmospheric The heated up 700 °C held for 15 h allow evolution. composition characterized scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD) photoelectron spectrum...
Mn-Co Spinel is considered as one of the most promising materials for interconnect protection solid oxide fuel cells; however, its conductivity too low to maintain a high cell performance compared with cathode materials. Element doping an effective method improve spinel conductivity. In this work, we proposed powder Cu via phase reaction. CuδMn1.5−xCo1.5−yO4 δ = 0.1, 0.2, 0.3, and x + y was obtained. X-ray diffraction (XRD) thermogravimetry-differential scanning calorimetry (TG-DSC) were...
A dynamic magnetic field (DMF) with different angular frequencies (50, 100, and 150 π rad/s) was introduced during diamond growth via hot filament chemical vapor deposition (HFCVD). The effects of the on rate, quality, orientation, uniformity large-area films were investigated scanning electron microscopy (SEM), X-ray diffractometry (XRD), Raman spectroscopy. correlation between frequency discussed. results showed that a faster rate (about 2.5 times) higher quality obtained by increasing...
Developing defects on the surface of TiO₂ nanoparticles by mechanical treatment is a fascinating approach to enhance photocatalytic efficiency. However, it poses risks producing bulk and phase transformation, which seriously deteriorates performance. Here, activating was elaborately fulfilled using dielectric barrier discharge plasma assisted ball milling (DBDP-milling) as imposes nano-scaled particles along with soft impact. The evolution properties DBDP-milling durations inspected Fourier...
