Copper-oxide brake nanofluid manufactured using arc-submerged nanoparticle synthesis system

This study examines the characteristics of copper-oxide brake nanofluid (CBN) manufactured using the arc-submerged nanoparticle synthesis system (ASNSS). Brake fluids containing copper nanoparticles are developed by melting bulk metal used as the electrode which is submerged in dielectric liquid. Copper is vaporized in brake fluid DOT3, which is used as an insulting liquid, and then rapidly quenched thus nucleating and forming nanocrystalline copper powders. The CBN thus obtained shows higher boiling temperature, higher viscosity and higher conductivity, which are affected by the synthesis parameters such as cooling liquid temperature and processing current. This study reveals that a home made machine can produce the CBN which higher boiling point to reduce the occurrence of vapor-lock, higher viscosity and higher conductivity thus showing superior performance of copper brake nanofluid.
