This study examines the feasibility of using the pulsed gas dynamic spraying (PGDS) process to deposit metal powder on the outer surfaces of metal wire mesh wafers for use as high-performance compact heat exchangers. Plain-square weave woven mesh produced from stainless steel wires were stacked and sintered to form wire mesh bricks, which were then cut into wafers. The outer surfaces of the wafers...... hiện toàn bộ
Preparation and Bond Properties of Thermal Barrier Coatings on Mg Alloy with Sprayed Al or Diffused Mg-Al Intermetallic InterlayerJournal of Thermal Spray Technology - Tập 23 - Trang 304-316 - 2013
Xizhi Fan, Ying Wang, Binglin Zou, Lijian Gu, Wenzhi Huang, Xueqiang Cao
Sprayed Al or diffused Mg-Al layer was designed as interlayer between the thermal barrier coatings (TBCs) and Mg alloy substrate. The effects of the interlayer on the bond properties of the coats were investigated. Al layers were prepared by arc spraying and atmospheric plasma spraying (APS), respectively. Mg-Al diffused layer was obtained after the heat treatment of the sprayed sample (Mg alloy w...... hiện toàn bộ
Fractal Evaluation on Effective Dielectric Properties for High-Velocity Oxygen Fuel Sprayed LBS-SiCβ Composite Absorber CoatingsJournal of Thermal Spray Technology - Tập 22 - Trang 723-733 - 2013

An evaluation of microstructure-property relationship is important for thermally sprayed composite absorber coatings, because self-similarity in the microstructure is a key characteristic that can affect coating properties, such as flattened particle shape, pores, absorbent phase, and coating thickness. In this paper, a multiscale effective fractal model is reported to characterize the microstruct...... hiện toàn bộ
Simulation of Motion, Heating, and Breakup of Molten Metal Droplets in the Plasma Jet at Plasma-Arc SprayingJournal of Thermal Spray Technology - Tập 24 - Trang 659-670 - 2015

The mathematical model for the process of plasma-arc wire spraying is proposed, which describes behavior of molten metal droplets in the plasma jet, allowing for the processes of their deformation and gas-dynamic breakup. Numerical analysis of the processes of motion, heating, and breakup of molten metal droplets, detached from the sprayed wire at plasma-arc spraying of coatings, was performed. It...... hiện toàn bộ
