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.

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。
