[en] A fundamental question to address in plasma-sprayed coatings is the existence and quantification of open porosity percolating in the through thickness direction. Percolating porosity was disclosed in a 25% porous vacuum plasma-sprayed tungsten (VPS-W, density: 14.85 g/cm"3) via high energy synchrotron X-ray microtomography (beam energy: 52 keV, voxel size: 1.4 μm). Micro-tomography revealed that at least 80% of the globular pores are interconnected and percolating across the coating thickness. The presented methodology can be useful in the design of infiltrated plasma-sprayed composites as well as for the identification of percolation thresholds in plasma-sprayed microstructures.
