采用溶液等离子喷涂和悬浮液等离子喷涂两种方法制备了多孔纳米结构WO3涂层。涂层的纳米结构特征可通过调节起始液体前驱体的成分和喷涂参数来调节。制备了尺寸可控的纳米级平面或球形WO3颗粒。在溶液等离子喷涂过程中获得了完整的球形WO3颗粒。通过增大等离子体功率对纳米WO3颗粒的加热，使WO3颗粒沿沿着（0 0 2）面取向生长。采用悬浮等离子喷涂技术制备了厚度约为50 nm、宽度约为80 nm、长度约为700 nm的平面状WO3颗粒。结果提供了清晰的洞察潜在的气敏应用的多孔WO3涂层。
Porous nanostructured WO3coatings were deposited by two routes, solution and suspension plasma spraying. The nanostructural characteristics of the coatings were tunable by adjusting the constituents of the starting liquid precursor and spray parameters. Planar or spherical WO3grains with controllable sizes in nano-scale have been fabricated. Complete formation of spherical WO3grains was attained during solution plasma spraying. Enhanced heating of the nano-WO3particles by augmenting plasma power gave rise to oriented WO3grain growth along (0 0 2) plane. The planar WO3grains with the dimension of ~50 nm, ~80 nm, and ~700 nm in thickness, width, and length respectively were fabricated by the suspension plasma spraying. The results provide clear insight into potential gas-sensing applications of the porous WO3coatings.
