Targets of Reduced Activation Ferritic Martensitic (RAFM) steel F82H were exposed to low-energy (200 eV), high flux (about 1022 D/m2s) deuterium (D) plasma at 623–773 K to various D fluences in the range from 1 × 1025 to 2.5 × 1026 D/m2. The surface morphology of the plasma-exposed targets was examined with a field-emission scanning electron microscope. Cross-sectional observations of nano-structures formed on the F82H target surfaces were performed using a transmission electron microscope equipped with an energy dispersive X-ray spectrometer. It has been shown that nano-sized fiber-like layers are formed on the target surfaces under D plasma exposure. Micro-sized surface morphology pattern depends on the D fluence. As the D fluence increases, clusters of the fiber-like layers begin to be formed and organized into ordered structure.

F82H钢在高温下暴露于低能D等离子体的表面形态

降低活化铁素体马氏体(RAFM)钢F82H的目标暴露于623-773 K的低能量(200 eV),高通量(约10 22 D / m 2 s)氘(D)等离子体中,范围从1×10 25到2.5×10 26 D / m 2。用场发射扫描电子显微镜检查暴露于等离子体的靶的表面形态。使用配备有能量色散X射线光谱仪的透射电子显微镜对在F82H目标表面上形成的纳米结构进行截面观察。已经显示出在D等离子体暴露下在靶表面上形成纳米级的纤维状层。微米级表面形态图案取决于D通量。随着D注量的增加,纤维状层的簇开始形成并组织成有序结构。
