“…4a). As previously stated, the bonding strength between the ceramic coating and the Mg substrate was increased by using metallic bond coat and compressed air during spraying [26,38]. In fact, the mismatch of the coefficients of thermal expansion was reduced and most of the residual stresses that occurred during spraying process were prevented by using metallic bond coat [40].…”

“…4c-f, the coating surface becomes smoother and denser. In fact, powder particles are injected into the plasma jet by an inert gas, melted (to different extents), and accelerated towards the substrate; thus, some melted particles spread out on the substrate and quickly solidified to form the smooth and lamellar structure, whereas some un-melted or partially melted particles easily build up some large agglomerations to form a rough surface with more microstructural defects such as splat boundaries, pores, and micro-cracks [38]. coating ( Fig.…”

“…In fact, well melted particles are able to spread out on the substrate well. Thus, the produced coating can firmly adhere to the substrate and provide relatively high bond strength [26,38]. Fig.…”

“…Different kinds of plasma spraying (PS) methods [27,28], as well as detonation spraying (DS), flame spraying (FS), and high-velocity oxygen-fuel spraying (HVOF) are in common use for depositing protective coatings from SHS powders [26,29,30].…”

UHTC composites were prepared by self-propagating high-temperature synthesis (SHS) from the Ti-B 4 C reaction system with addition of Cr, Mo, and W. The starting sample composition was formulated as (3−x)Ti + B 4 C + xMe with x = 0.1-1.0 and Me = Cr, Mo, or W. For all samples conducted in this study, self-sustaining combustion was well established and propagated with a distinct reaction front. With no addition of Cr, Mo, or W, solid state combustion of the 3Ti + B 4 C sample featuring a combustion front temperature (T c ) of 1766 • C and a combustion wave velocity (V f ) of 16.5 mm/s was highly exothermic and produced an in situ composite of 2TiB 2 + TiC. When Cr, Mo, or W was adopted to replace a portion of Ti, the reaction exothermicity was lowered, and hence, a significant decrease in T c (from 1720 to 1390 • C) and V f (from 16.1 to 3.9 mm/s) was observed. With addition of Cr, Mo, and W, the final products were CrB-, MoB-, and WB-added TiB 2 -TiC composites. The absence of CrB 2 , MoB 2 , and WB 2 was attributed partly to the loss of boron from thermal decomposition of B 4 C and partly to lack of sufficient reaction time inherent to the SHS process.

“…Various surface treatments including spraying, electroplating, PEO, chemical conversion, anodic oxidation, organic coatings, PVD, have been proved to be available [14][15][16][17][18][19][20]. Of these, one promising approach is to treat magnesium alloy using the PEO technique.…”
