摘 要
本文針對AA6063-T5鋁合金管材，利用萬能試驗機與一部專門量測導引區的液壓摩擦試驗機，並使用 (1)液體、(2)固體、(3)半固體等各種潤滑劑對導引區進行一系列的管材液壓摩擦試驗，以求得摩擦係數值。經由不同潤滑劑試驗結果，獲得固體潤滑劑的潤滑效果是最好的，而液體潤滑劑的潤滑效果是較差的。由不同的內壓力試驗獲得當內壓力越高時，摩擦係數會略往下降。由不同的滑動速度試驗獲得速度在100 mm/min範圍內對摩擦係數的影響是不大的。並藉由粗度儀與光學儀器CCD獲得AA6063-T5管材實驗過後之表面情形。

ABSTRACT
The objective of this study is to obtain the friction coefficient of lubricants in tube hydroforming of guiding zone. Lubricants, universal testing machine, and friction test machine in tube hydroforming of guiding zone are used to carry out the experiments of aluminum alloy tubes. Lubricants are categorized according to their performance as follows: (1) oils, (2) emulsions, and (3) slide lacquer. Different lubricants tests, it is known that the best lubrication is derived from slide lacquer, while oils showed the poorest behavior. Different internal pressure tests, it is known that greater internal pressure causes the coefficient of friction decreasing. Different sliding velocity, it is known that sliding velocity does not affect the coefficient of friction at 100mm/min. And using CCD which is an optical instrument obtains the surface of tubes after experiments.
