TL;DR: In this paper, the effect of splat interfaces on the effective thermal conductivity and elastic modulus along the spray, as well as the transverse directions are estimated for thermally sprayed yttria-stabilized zirconia (PSZ) coatings.

TL;DR: In this article, the authors examined three thermal spraying techniques with significantly different particle temperatures and velocities, including air plasma spraying (APS), twin wire-arc spraying (TWA), and high velocity oxy-fuel (HVOF) spraying.

TL;DR: In this paper, an image analysis (IA) method was used for characterization of porosity in thermally sprayed coatings and the results were complemented with the microstructural information obtained using advanced characterization techniques, such as small-angle neutron scattering (SANS) and computer micro-tomography (CMT) carried out on similar coatings.

TL;DR: In this paper, microstructure parameters determined by SANS studies are then assembled into a preliminary model to develop a predictive capability for estimating the properties of these coatings, and thermal conductivity and elastic modulus were predicted using finite element analysis and ultimately compared to experimental values.

TL;DR: In this article, the influence of feedstock characteristics on particle state in the plasma and the resultant coating properties is addressed, which shows increased porosity with particle size, due to an increase in the degree of particle fragmentation and unmelted particles, leading to lower thermal conductivity and modulus.
