Study of in-flight and impact dynamics of non-spherical particles from HVOF guns [PDF]

open access: yes, 2009
High velocity oxygen fuel thermal spray has been widely used to deposit hard composite materials such as WC-Co powders for wear-resistant applications. Unlike gas atomized spherical powders, WC-CO powders form a more complex geometry.

Mechanism of vertical crack formation in Yb2SiO5 coatings deposited via plasma spray-physical vapor deposition

open access: yesJournal of Materiomics, 2020
Plasma spray-physical vapor deposition (i.e., PS-PVD) is a promising method for obtaining advanced environmental barrier coatings (EBCs). The EBCs must meet some requirements in the application, in which the thermal cycle performance affects the service ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
