In this work, using elemental powders as starting reactant materials several carbide powders such as wc, sic, tic, zrc and corresponding alloys had been fabricated by ball - milling technique. x - ray diffraction ( xrd ), scanning electron microscopy ( sem ), transmission electron microscopy ( tem ) and other measurement techniques had been used to monitor the structural changes of powders after some ball milling time and the properties of the cemented tungsten carbides. and the mechanism for the formation of matal carbides by ma has also been discussed
本文主要對機械合金化（ ma ）技術在碳化物制備中的應用進行了研究，利用高能球磨，以元素粉末為原料，制備出wc 、 sic 、 tic 、 zrc的粉體以及wc基硬質復合材料，並利用x射線衍射、掃描電鏡、透射電鏡等方法分析和研究了球磨過程粉體的變化以及燒結后硬質合金的性能，對機械合金化制備碳化物的有關機理進行了研究和探索。 -
In order to research systematically the kinetics of the redox reaction between tbh and np ( vi ), the main contents of the work in this paper are as follows. ( 1 ) tbh is synthesized by direct alkylization in chsoh media. the structure and composition of the product are characterized by elemental analysis, uv - vis spectrum, ir spectrum, ms spectrum and nmr spectrum respectively
