Preparation method of vanadium slag/sodium carbonate diffusion couple
The invention relates to a preparation method of a vanadium slag/sodium carbonate diffusion couple, and belongs to the technical field of material research methods. The method comprises the following steps: embedding a graphite wafer into vanadium slag powder, pressing a vanadium slag sheet at normal temperature, then pressing the vanadium slag sheet at high temperature, and separating the vanadium slag sheet from the graphite wafer through high-temperature calcination to obtain the vanadium slag sheet with a groove; and pressing a sodium carbonate sheet at room temperature, placing the sodium carbonate sheet in the vanadium slag sheet with the groove for diffusion reaction, and cooling to obtain the diffusion couple. The diffusion couple prepared by the method is a liquid-solid diffusion couple, two components are in sufficient and close contact, and the diffusion is sufficient; economy and safety are realized; the method is easy to operate and is a reasonable and effective method for preparing the vanadium slag and sodium carbonate diffusion couple.
本发明涉及一种钒渣/碳酸钠扩散偶的制备方法，属于材料研究方法技术领域。该方法包括将钒渣粉末中埋入石墨圆片进行常温压制钒渣片，之后高温压制钒渣片，通过高温煅烧分离钒渣片与石墨片获得具有凹槽的钒渣片；室温压制碳酸钠片，将碳酸钠片置于具有凹槽的钒渣片中进行扩散反应，降温后获得扩散偶。本发明方法制备出来的扩散偶是一种液‑固扩散偶，两组分充分、紧密接触，扩散充分；经济安全；操作简单，是一种制备钒渣与碳酸钠扩散偶的合理有效方法。
