Abstract:
The invention relates to a method comprising the following steps of: providing a grafting device (20) including a torch (26) that produces a flame (28) in a volume of ambient air and a cooling substrate (33) positioned facing the flame (28); moving the elongate material (14) continuously through the flame (28) between the torch (26) and the cooling substrate (33); and grafting carbon nanostructures (16) continuously onto the elongate material (14) during its passage through the flame (28).
Abstract:
A thermal barrier coating that includes a YAG-based ceramic is prepared by a solution precursor plasma spray method that includes injecting a precursor solution into a thermal jet, evaporating solvent from the precursor solution droplets, and pyrolyzing the resulting solid to form a YAG-based ceramic that is melted and deposited on a substrate. The thermal barrier coating can include through coating-thickness cracks that improve the strain tolerance of the coating.
