【摘要】 奈米氧化铝煞车油(Nanobrake fluids)系由本校自行设计之电浆放电奈米制造系统生产,电浆电弧放电所产生之高温将铝钯材瞬间汽化产生奈米颗粒氧化铝,以压力差将汽化金属吸入冷却液(Dot3),而奈米氧化铝会均匀融入冷却液而得奈米氧化铝煞车油．对于所生产出奈米悬浮氧化铝颗粒大小进行检测分析,经由穿透式电子显微镜(TEM),X 光绕射仪(X-ray)来界定所生产之奈米悬浮液之外观以及组成成分并对煞车油共沸点及粘度特性,做一具体之探讨;生产之奈米粒径约为30 nm奈米氧化铝粒,平均粒径也可达到50 nm左右,而奈米氧化铝流体颗粒之外形呈现圆形度分布均匀提供煞车系统较低起始摩擦力,同时提升煞车油共沸点及粘度性能增加煞车安全性．更多还原

【Abstract】 This study examines the characteristics of aluminum-oxide brake nanofluid (ABN) manufactured using the plasma arc system. The ABN thus obtained shows higher boiling point, higher viscosity and higher conductivity, which are affected by the synthesizing parameters such as cooling liquid temperature and processing current. This study reveals that a home made machine can produce the ABN which surpasses the boiling point to reduce the occurrence of vapor-lock, the higher viscosity and the higher conductivity thus showing superior performance of brake nanofluid.更多还原
