Producing thermal barrier comprises depositing layer of platinum metal on super alloy substrate, and depositing layer of thermal barrier on layer of platinum metal by plasma thermal spraying including plasma spray atomization method
Producing thermal barrier comprises depositing layer of platinum metal on super alloy substrate, and depositing layer of thermal barrier on layer of platinum metal by plasma thermal spraying including plasma spray atomization method
The method comprises depositing a layer (20) of platinum metal on a super alloy substrate (10), and depositing a layer of a thermal barrier on the layer of platinum metal by plasma thermal spraying including plasma spray atomization method. The thermal barrier layer is a metal alloy sublayer. The platinum metal layer is deposited on the substrate without induction of surface roughness of substrate by sandblasting, and has a thickness of 3-7 mu m. The method further comprises depositing a layer of a ceramic thermal protection on the metal alloy sublayer.
