Description

Abstract
" 本計畫係針對奈米金鋼石(或稱鑽石)超分散潤滑劑,在進行整合研究計 畫前所進行的前導研究。主要的目的在透過有系統的實驗量測與儀器觀 察,瞭解該潤滑劑的流變性質與流體的結構,做為進一步建立流場模型的 基礎,並援引為深入研究時調整實驗與研究方向之用。計畫中除了基本的 粉體物性檢測外,主要在透過多功能流變儀的量測,將含有不同濃度之金 剛石粉體(粒徑約3~10nm 大小)的潤滑劑,在改變溫度、壓力下量測其應 變率與剪應力的關係。藉以探討包括:黏度變化、遲滯特性、流變模型, 以及碎形維度。進而建立該流體之濃度應變率之適用圖表,並探討該懸浮 微粒與液體的微觀作用機制。 "
