“…The microstructure of the coating A3 suggests it to be the most porous of the SPS coatings investigated here; thus, it is feasible that a denser SPS coating could have an erosion rate on par with a DVC coating. Cernuschi et al [30] conducted a more detailed study comparing DVC structured APS coatings with EB-PVD coatings. Their work suggests that the erosion rates of EB-PVD and DVC structures are similar.…”

“…To understand the erosion mechanism for PS-PVD it is first helpful to examine what is known for EB-PVD and APS erosion as these mechanisms have been heavily covered in the literature [18,28,[30][31][32][33][34] while erosion of PS-PVD has seen minimal investigation [20,35]. The velocities and particle sizes used in this study fit into the Mode I regime as described by…”

“…For instance, the characteristic columnar microstructure of Electron Beam -Physical Vapor Deposition (EB-PVD) typically offers an order of magnitude improvement in erosion durability compared to a standard lamellar Air Plasma Spray (APS) coating [18]. Recent work has investigated methods to improve the durability of APS coatings via dense vertical cracking and deposition from small particle suspensions or precursor solutions [19,20]. The common factor in each of these methods is the formation of a vertically oriented porosity that inhibits lateral cracking and promotes strain tolerance, yielding erosion rates approaching EB-PVD.…”

“…A number of researchers have also studied the solid particle erosion wear of plasma sprayed traditional ceramic coatings. [16][17][18][19][20][21][22][23][24][25] Branco et al 16 examined solid particle erosion of zirconia and alumina based ceramic coatings with different levels of porosity and concluded that there was a strong relationship between erosion rate and porosity. Westergård et al 20 studied the influence of different spraying conditions on the erosion resistance of plasma sprayed alumina coatings.…”
