本工作提出一种新的辐照损伤合金化方法,首先采用离子注入技术将离子束注入金属,使其产生包括空位在内的辐照损伤,然后利用辐照损伤来诱发互不固溶金属之间的扩散和合金化,从而实现金属界面之间的冶金结合.扩散层中形成的非晶合金相是形成冶金结合的关键.基于该辐照损伤合金化机制,制备出了高性能的空间飞行器太阳能电池阵互连片用Mo/Ag层状复合材料,这种材料与空间GaAs电池片的单点电阻点焊拉伸强度最高达到了150 MPa,平均为130 MPa,超过了国家军用标准和航天用户提出的指标要求.
This work proposed a new radiation damage alloying method, the first ion implantation technology will be injected into the ion beam to produce radiation damage, including the empty space, and then use the radiation damage induced by the mutual non-dissolved metal Between the diffusion and alloying, in order to achieve the metallurgical bonding between the metal interface.The amorphous alloy phase formed in the diffusion layer is the key to the formation of metallurgical bonding.Based on the irradiation damage alloying mechanism, a high performance space vehicle Solar cell array interconnection with Mo / Ag layered composite material, this material and space GaAs single-point spot resistance spot welding up to 150 MPa, an average of 130 MPa, exceeding the national military standards and aerospace User-made index requirements.
