采用强流脉冲离子束技术对金属玻璃Zr 55 Al 10 Cu 30 Ni 5和W金属进行表面辐照处理。在250 kV的加速电压下，在不同的能量密度和不同的脉冲数下，离子束主要由Cn+（70%）和H+（30%）组成。XRD分析表明，HIPIB辐照后金属玻璃的主要结构保持非晶，没有明显的晶相存在。扫描电镜分析表明，在低辐照频率下，金属玻璃表面没有明显的辐照损伤（3次和10次）;多次辐照后金属玻璃表面出现“花瓣”状辐照损伤（100倍和300倍），并且花瓣中心的组成包括Fe和Cr，离子二极管阴极的组成，除了Zr基金属玻璃的组成之外。透射电镜分析表明，只有在300倍的辐照下，才产生少量的纳米晶Zr 2Ni型相（面心立方）。辐照100次和300次后，W表面出现裂纹，在能量密度为1.4 J/cm 2和2.0 J/cm 2时，W表面甚至出现脱落现象。辐照金属玻璃表面纳米硬度降低。
High intensity pulsed ion beam technology was used for the surface irradiation treatment of metallic glass Zr55Al10Cu30Ni5and W metal. The ion beam was mainly composed of Cn+(70%) and H+(30%) at an acceleration voltage of 250 kV under different energy densities for different number of pulses. XRD analysis showed that the metallic glass remained amorphous in its main structure after HIPIB irradiation, without apparent presence of crystalline phases. SEM analysis concluded that there was no apparent irradiation damage on the surface of metallic glass at the low irradiation frequency (3 times and 10 times); “petal”-shaped irradiation damage appeared on the surface of metallic glass after multi-irradiation (100 times and 300 times), and the composition of the petal center included Fe and Cr, the composition of an ion diode cathode, in addition to the composition of Zr-based metallic glass. TEM analysis of irradiated metallic glass showed that a small amount of nanocrystalline Zr2Ni-type phase (face centered cubic) was produced only at 300-time irradiation. Cracks appeared on the surface of W after 100-time and 300-time irradiation; shedding phenomenon even appeared on the surface of W at the energy densities of 1.4 J/cm2and 2.0 J/cm2. The surface nano-hardness of irradiated metallic glass decreased.
