“…[25,26] Spray forming, also known as spray atomization and deposition, is a solidifi-cation processing technology, which was recognized as a special powder metallurgy process (a new type of molding process based on the powder metallurgy). [27][28][29] Spray-formed superalloy has a similar microstructure to the conventional PM superalloy, and it has some advantages of fine-scale microstructure, lower levels of oxygen and short procedure. [30][31][32] Explorations for performances of the spray-formed materials are in progress.…”

An investigation of low temperature hot corrosion is carried out on a spray-formed nickel-based superalloy FGH100 pre-coated with Na 2 SO 4 -NaCl at 700 • C for 100 h. Mass gain measurement, x-ray diffraction, scanning electron microscopy, and energy dispersive x-ray spectroscopy are used to study the corrosion behavior. Results reveal that corrosion behavior follows a sequence, that is, first rapidly proceeding, then gradually slowing down, and finally forming an outer layer composed of different types of oxides and an inner layer mainly comprised of sulfides. In-depth analysis reveals that the hot corrosion of FGH100 is a combined effect of oxidation-sulfidation and transfer of oxides.

“…Particle reinforced metal matrix composites have many good properties such as low cost enhanced body, uniform microstructure, isotropic material properties, good machining performance etc and hence draw much attention [4].A large number of domestic and foreign scholars' experiments show that alloy's properties can be improved and enhanced with the particles added [5][6][7]. A new rapid solidification technique-spray deposition draw much attention in recent years for its short process, low cost, high deposition efficiency, near-net-shape forming, product diversity, etc [8]. Some researches show that zinc-aluminum alloy produced by spray deposition has greater mechanical properties and wear resistance than conventional cast alloy [9].…”

An innovative spray deposition technique has been applied to produce in situ TiB2/Zn-30Al-1Cu composites. The microstructures of the spray-deposited composite were studied using optical microscopy, scanning electron microscopy, and X-ray diffraction. Both theoretical and experimental results have shown that the TiB2particulates are formed in the microstructure. It was found that the TiB2particles were distributed in Zn-30Al-1Cu matrix uniformly, and the TiB2particles are about 2 μm in size. Moreover, the presence of the TiB2particles was led to increasing of α’ phase with less 2 μm size in the composites which have a tendency to decompose to α+η structure.

An innovative spray deposition technique has been applied to produce in situ TiB2/Zn-30Al-1Cu composites. The microstructures of the spray-deposited composite were studied using scanning electron microscopy, transmission electron microscope and X-ray diffraction. The results have shown that the TiB2particulates are formed in the microstructure. It was found that the TiB2particles were distributed in Zn-30Al-1Cu matrix uniformly, and the TiB2particles are about 2μm in size.
