铬-铝氧化物复合阻氚涂层的制备工艺研究
Study on preparation process of chromium-aluminum oxide composites tritium permeation barrier
摘要
Abstract
Due to the small atomic radius and high reactivity, tritium (T) can easily penetrate into the inner of cladding structure and release to the environment, which causes the deterioration of cladding structure materials, loss of tritium, and irradiation pollution. Therefore, Tritium permeation barrier (TPB) plays an important role in the tritium-proliferating cladding for fusion reactor. Oxide composites TPB has some good performances, such as simple preparation process, chemical stability, and high melting point, and becomes a research hotspot in fusion reactor materials in recent years. In this paper, the chromium oxide and aluminum oxide composites coatings were prepared on inner wall of metal pipe by chemical plating, combined with molten salt electrodeposition and atmosphere oxidation process, and the microstructures, thickness, and binding force of coatings were investigated. The results present that, the surface microstructures of oxide composites coating are uniform and compact. The thickness and porosity of chromium oxide and aluminum oxide composites coating are 10~40μm and 7%~8%, respectively. The binding force between coating and substrates is more than 20 N.关键词
