中文摘要 | 本文以考慮到化學反應及氣體擴散的粉粒模式來解說鈦顆粒的直接氮化反應。在 不同的反應控制區內,鈦顆粒內的反應形態是不同的。文中示出在顆粒內不同地點粉粒內的 反應正面移動。 我們利用部份反應的照片及 X 光繞射所測得固體反應物及生成物的濃度輪 廓來證實模式的可靠性。 |
英文摘要 | Direct nitridation of titanium pellet is generally treated based on a grain model of gas-solid reaction in which chemical reaction and pore gas diffusion are taken into consideration. The morphologies of reaction fronts in the titanium pellet in various control regions are different. The progress of the reaction front of the grain of different position in the pellet has been shown in this study. Photographs of partially reacted pellet and concentration profiles of solid reactants and solid products determined by X-ray diffraction, are used to verify the model predictions. |
