摘要
采用磁控溅射结合离子束混合技术在不锈钢基体上制备C-(50～90)%SiC涂层,对涂层进行加热处理及氢离子注入。对各种条件下制备的涂层进行元素深度分布分析。结果表明,SiC组分含量高的涂层具有更好的阻氢性能,而C组分含量高的涂层与基体具有更好的结合性能,综合考虑今后在氚废物包装桶涂覆的实际使用工况来看,采用C-(75～85)%SiC作为涂层似乎更合适些。通过对涂层阻氢性能的分析发现,C-SiC涂层经加热处理后,涂层的阻氢能力得到进一步的提高,并且可以提高氢离子在涂层中的稳定性。
The C-（50-90）%SIC coatings were prepared on stainless steel by magnetron sputtering combined with the ion beam technology in order to improve the hydrogen resistance of stainless steel. These samples were thermally treated in different conditions and then implanted with H ＋ ions to simulate the environmental status and to offer the basis datas for their applications in the future. The depth profiles were analyzed for different coatings. The results show that the coating with high SiC content has good hydrogen resistance and the coating with high C content has good combination with the substrate. The compactability and the hydrogen resistance were improved with ion beam mixed more times. The hydrogen resistance was further improved with heating to remove argon and also the thermal stability of hydrogen in coatings was improved.
