tungsten carbide ball 中文意思是什麼
tungsten carbide ball
解釋
碳化鎢磨球-
The unstable solid solution would disintegrate and transform into carbide phases in these systems of sisocso, tisocso and zrsocso, based on the increase of free energy introduced by the effect mechanical alloying. for the system of wsocso, the solid solution had not transformed into tungsten carbides but an amorphous phase, which was different from those systems. the exist of fe in these experiments, which came from the abrasion of ball - milling tool because of the higher hardness of w and w - c solid solution, would induce the crystalline - to - amorphous phase transformation during milling
C50球磨體系中，繼續球磨時，不穩定的固溶體在機械合金化作用下，由於體系能量提高，會發生分解相變，從而可以形成碳化物；對于w扣c50球磨體系， w ? c固溶體具有較高的硬度，磨削不銹鋼質的球磨介質和球磨容器，而引入雜質，其中fe會促使固溶體向非晶相轉變。 -
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。 -
The mixture of tungsten and graphite powders would tranform into solid solution by ball milling for little time, and wc with high purity was obtained by treatment at a lower temperature. the milling time, producing energy and the disadvantage of contamination was reduced, which is favorable for the future application in the manufacture of tungsten carbide
W 、 c粉體經過短時間球磨形成固溶體后，較低溫度下退火就可以得到純度很高的wc ，可以大大縮短球磨時間，從而避免了過渡的污染而且降低了能耗，具有工業實際應用前景。
