Název v původním jazyce
Unique wettability phenomenon of carbon-bonded alumina with advanced nanocoating
Popis výsledku v původním jazyce
In this paper, a unique nano-coating consisting of a mixture of graphene oxide and multi-walled carbon nanotubes was applied on carbon-bonded alumina substrates. Graphene oxide (GO) was prepared according to the modified Tour's method. GO in combination with carbon nanotubes (CNTs) and modified coal tar pitch was spray-coated on conventional carbon-bonded alumina material for investigations in contact with steel. Temperature and time-dependent experiments were performed in a hot stage microscope to analyze the wetting behavior. The microstructures of the substrates before and after heating were compared by scanning electron microscopy. The results showed that the coating containing both GO and CNTs delivered a fast stabilization of the wetting angle with low wettability towards the metal melt. Similar coatings may offer an innovative approach to improve purification of steel melts by filtration in the steel industry.
