Correlations between processing parameters and microstructure for YSZ films produced by plasma spray technique

Deposition of nanostructured YSZ coating from spray-dried particles with no heat treatment

“…Furthermore, previous studies [14][15][16] have also elucidated that extraordinary properties can be obtained with a nanostructure closer to its original size (especially less than 100 nm). It is necessary to control the starting nano-crystal size of the agglomerates and their heat trajectories carefully in the plasma jet [17,18]. Many investigations have been completed to connect jet temperature with coating microstructures by studying the effects of spray processing parameters [19].…”

Microstructure and properties of plasma sprayed Al-doped YSZ coatings

“…The experimental procedure, equipment, and operating conditions have been described in detail elsewhere [7,8]. Stainless steel substrates were used for microstructural investigation, and substrates of alloy-600 for ionic conductivity measurements.…”

Porosity and microstructural features of plasma sprayed Yttria stabilized Zirconia thermal barrier coatings

“…Any deviation from the optimal deposition condition leads to formation of poor coatings with defective coating microstructure and weak coating/substrate interface. Insufficient coating to substrate adhesion, increased crack density induced by the release of residual stress, high density of un-melted and partially melted particles and undesired porosity content are common problems encountered in coatings deposited far from the optimum conditions [9,10].…”
