Preparation of Foam Ni/Carbon Nanotubes Material for Enhanced Stationary Seal Ring
Stationary seal ring, the mainly units of mechanical seal, its anti-lacking function mostly depends on the material performances. For enhanced stationary seal ring’s thermal conductivity, self-lubrication and strength, in this paper authors prepared a kind of composite material with reticular formation that is foam Ni-carbon nano tubes (Foam Ni/CNTs) as the reinforced element for stationary seal ring’s resin matrix. The experiments using Fe-Co/CNTs as catalyst via chemical vapor deposition (CVD) method prepared four groups samples with different decomposition temperature and tested by SEM and Raman spectra. The result shows that the temperature at 550°C, carbon nano tube obtained better crystallization effect and the reticular structure of foam Ni also integrity. The foam Ni/CNTs presented one kind of new reinforced phase for mechanical seal material design.
