The former work proved that ion irradiation causes the amorphization of the crystalline MoS₂ film and leads to the degradation of the lubricating performance. In this work, in order to investigate the influence of irradiation damage on the amorphous structure, MoS₂ film with amorphous structure was prepared and ion (Au²⁺) irradiation experiment was performed with damage level up to 5 dpa. The results show that after irradiation, the short-range order structure in the amorphous MoS₂ film is interrupted, and the degree of disorder of its internal atoms increases. With the increase of the irradiation fluence, although the hardness and elastic recovery of the film increases significantly, the wear lives of the film reduce by two third. Further friction interface analyses reveal that the irradiation damage MoS₂ film formed less reordered transferred layer at counter face, which leads to the higher friction coefficient and the shorter wear life.

前人的工作证明，离子辐照导致结晶MoS ₂薄膜的非晶化，导致润滑性能下降。在本工作中，为了研究辐照损伤对非晶结构的影响，制备了具有非晶结构的MoS ₂薄膜，并进行了离子（Au ²⁺）辐照实验，损伤水平高达5 dpa。_{结果表明，辐照后，非晶MoS 2}中的短程有序结构膜被打断，其内部原子的无序程度增加。随着辐照能量密度的增加，虽然薄膜的硬度和弹性回复率显着提高，但薄膜的磨损寿命减少了三分之二。进一步的摩擦界面分析表明，辐照损伤MoS ₂薄膜在反面形成较少的重排转移层，导致摩擦系数较高，磨损寿命较短。
