| 摘 要： | 316L不锈钢是聚变堆包层候选结构材料,为解决其氚渗透率较大的缺点,在使用中必须采用防氚渗透涂层.目前看来,铝基涂层发展潜力最大.采用热浸镀铝法在不锈钢表面制备铁铝层,并分析了镀层的组织结构以及温度和合金元素对其厚度的影响.结果表明:热浸镀纯铝后,镀层由表面铝层和合金层组成,随浸铝温度的升高,外层铝层减薄,而内层合金层增厚明显,镀层总厚度并没有太大差异;加入合金元素硅对减薄镀层的作用明显.

| Abstract: | One of the main issues in the design of blankets for a future fusion reactor is the permeation of tritium through the structure material into the secondary circuit.It is well known that thin alumina layer can reduce the hydrogen permeation rate by several orders of magnitude.A technique of hot dip aluminizing process that preparing Fe-Al film on surface of stainless steels have been studied.The results show that,according to experiments that have been done in pure Al,two distinct regions of the coating coul... |
