摘要:

金屬鈾因具有優(yōu)異的放射性能在國防和核能領(lǐng)域具有重要的戰(zhàn)略價(jià)值。然而，由于鈾具有高的反應(yīng)活性，在大氣環(huán)境中極易被腐蝕。在眾多防腐技術(shù)中，表面處理技術(shù)被廣泛用來提高鈾的耐腐蝕性能。聚焦鈾表面防腐的需求，重點(diǎn)綜述了表面合金化、電鍍、離子注入、離子鍍等鈾的防腐技術(shù)的研究進(jìn)展，并針對不同技術(shù)目前面臨的難題，展望了其未來的發(fā)展。近年來，離子注入、離子鍍技術(shù)成為鈾防腐領(lǐng)域的研究重點(diǎn)，具有很大的發(fā)展?jié)摿�。然而，金屬鈾的防腐性能仍需更進(jìn)一步提高，復(fù)合沉積技術(shù)可以結(jié)合各種技術(shù)的優(yōu)點(diǎn)，有望制備出耐蝕性更好的鈾表面防腐涂層。此外，高功率脈沖磁控濺射技術(shù)在防腐領(lǐng)域擁有較大的應(yīng)用潛力，是制備鈾表面高性能防腐涂層的潛在方法，值得進(jìn)一步研究。另一方面，合理利用鈾的氫化腐蝕特性，可能使該材料成為一種優(yōu)秀的儲氫材料。

Abstract:

Uranium is widely used in the fields of national defense and nuclear energy because of its high density and excellent nuclear performance. However, uranium is easily corroded in corrosive environment due to its high reactivity. Surface treatment technology is widely used to improve the corrosion resistance of uranium. This paper focuses on the requirements of uranium surface anti-corrosion.The research progress of uranium corrosion protection technologies including surface alloying, electroplating, ion implantation and ion plating is reviewed. The future development of different technologies is prospected according to the current problems. At present, the ion implantation and ion plating have become the focus in recent years and have great development potential. However, the corrosion resistance of uranium metal still needs to be further improved. Composite deposition technology can combine the advantages of various technologies and it is expected to prepare uranium corrosion resistant coatings with better corrosion resistance. In addition, high-power pulsed magnetron sputtering technology has great application potential and is a potential method to prepare high-performance uranium anticorrosion coatings, which is worthy of further study.On the other hand, uranium can become an excellent hydrogen storage material by making rational use of its hydrogen corrosion characteristics.
