Effect of hydroxyl groups in PVB on the microstructure of electrophoretically deposited green bodies for thermal barrier coatings

Thermal conductivity of polymer composites with oriented boron nitride

“…The degree of orientation is highest for BN/PVA composites across the entire BN content range due to their higher number of hydroxyl groups. PVA contains 80-90% hydroxyl groups in its chemical formula, while PVB contains just 20%; so, the hydrogen bonding of BN/PVA composites is stronger [10,11]. For the BN/polymer composite with 0.5 V f BN, the amphiphilic-agent-treated BN/polymer composites showed a higher degree of orientation than that of non-treated composites.…”

Fabrication and characterization of functionally graded hydroxyapatite/TiO2 multilayer coating on Ti–6Al–4V titanium alloy for biomedical applications

“…Higher value of zeta potential shows higher surface charge on the particles in suspension that avoids particles agglomeration. This leads to have stable suspension in which the particles remain dispersed for a long time [21][22][23]. The ζpotential of HA and TiO 2 particles in different suspensions were measured and the results are shown in Fig.…”

Fabrication of Yttria‐Stabilized Zirconia Coatings Using Electrophoretic Deposition: Packing Mechanism During Deposition

“…E lectrophoretic deposition (EPD) has been applied extensively to form both thin and thick ceramic coatings on planar or complex‐shaped substrates 1–3 . One potential application of EPD is to fabricate thermal barrier coatings (TBCs) on engine components for protection from high‐temperature environments 4,5 . In comparison with air plasma spray (APS) and electron beam physical vapor deposition (EP‐PVD), which are both used widely for TBCs fabrication, the EPD technique has the following advantages: no restriction on substrate shape, simple fabrication technique, low‐cost process, controlled microstructure, and high deposition rate.…”
