Effect of in-flight particle characteristics on the coating properties of atmospheric plasma-sprayed 8mol% Y2O3–ZrO2 electrolyte coating studying by artificial neural networks

Sensing properties of atmospheric plasma-sprayed WO3 coating for sub-ppm NO2 detection

“…It has an important influence on the temperature of the in-flight particles and ultimately on the microstructure of the deposited coatings. In a previous study [36], the effect of the H 2 flow rate on the microstructure of ZrO 2 coatings was studied. The diagnostic results of the ZrO 2 inflight particle characteristic showed that the particle temperature decreased significantly when the H 2 flow rate was reduced.…”

Automated image inspection system to quantify thermal spray splat morphology

“…This way, it is possible the development of an image inspection system that acquires SEM images, and without human intervention, it decides whether the coating or the spraying parameters are acceptable. 10. Decision tree for the determination of the different types of splat labelled by the procedure as a function of circularity, eccentricity, and solidity.…”

“…The coating properties are mainly determined firstly by the conditions of the impacting particles such as size, velocity, temperature, oxidation and phase [6][7][8][9][10][11]; and secondly by the substrate conditions such as thermophysical properties, wetting ability, surface roughness, temperature, presence of condensates and adsorbates, and thermal contact resistance [12][13][14][15][16][17]. All these conditions affect the way a splat solidifies on the substrate.…”

Modelling of Alumina Splat Solidification on Preheated Steel Substrate Using the Network Simulation Method

“…and the second and third ones as: Figure 4 represents a cell inside the network model. In this circuit, the terms in Equations (8) and (9) are equivalent to electric currents, IB or IR, respectively, which are balanced in a common node.…”

“…After impact, the particles solidify on the substrate producing thin and dense lamellae or layers, called splats, whose shape depends on the size, shape and powder material properties, flying particle temperature and impact velocity and roughness and temperature of the substrate, in short, heat transfer and flow fluid. The coating's main characteristics, the adhesion strength on the substrate and the residual stresses generated at the interface depend on these properties [1,[4][5][6][7][8][9][10][11][12][13][14][15][16].…”
