采用锂陶瓷、液态锂铅为氚增殖剂是当前国际上两类主流聚变堆氚增殖包层,两者皆采用低活化铁素体/马氏体(RAFM)钢(如欧洲的Eurofer97、日本的F82H、中国的CLAM等)作为结构材料。为有效解决包层的氚包容尤其是液态锂铅耐蚀和磁流体动力学等问题,目前国际上普遍选择在RAFM钢表面制备铁铝化物-氧化铝(Fe-Al/Al2O3)复合涂层作为首选解决方案。粉末包埋渗铝+原位氧化是在包层复杂结构表面制备Fe-Al/Al2O3复合涂层最可行的工艺之一。针对液态锂铅相容性
The use of lithium-ceramic, liquid lithium lead as a tritium multiplier is currently the world’s two mainstream fusion reactor tritium proliferation cladding, both using low activation ferrite / martensitic (RAFM) steel (such as Europe’s Eurofer97, Japan F82H, China’s CLAM, etc.) as a structural material. In order to effectively solve the problems of tritium inclusion, especially the corrosion resistance of liquid lithium lead and magnetic fluid dynamics, the Fe-Al / Al 2 O 3 composite coating on RAFM steel is widely used internationally Preferred solution. Powder-embedded aluminizing + in-situ oxidation is one of the most feasible processes for preparing Fe-Al / Al2O3 composite coating on the surface of complex cladding structure.
