摘要：

采用纳米压痕技术对60Co ?-射线辐照改性前后As2S3玻璃的表面机械性能(即硬度和弹性模量)进行超纳硬度仪(UNHT) 测试，压痕深度为 200~1 600 nm。结果表明：经平均量子能 1.25 MeV、累计剂量 2.41 MGy 的 60Co ?-射线辐照后，g-As2S3(g表示玻璃态)的表面硬度和弹性模量与辐照前相比得以提高。对于 g-As2S3表面机械性能的长期辐照诱导改性，具有辐照诱导氧化层的辐照样品与经过清洗和抛光处理除去氧化层的辐照样品相比，其实验数据显示宽分布特性。

The results of the surface mechanical properties (i.e., hardness and elastic modulus) in the unmodified and radiation-modified As2S3 glass measured about after 60Co ?-irradiation, using a nanoindentation technique with an ultra nano hardness tester (UNHT) were reported. It is indicated that the ?-irradiated g-As2S3 (g- for glassy) with the average energy of 60Co ?-quanta of 1.25 MeV and the accumulated dose of 2.41 MGy exhibits the increased surface hardness and elastic modulus values, compared to the unirradiated material, in the range of 200–1 600 nm indentation depth. In the long-term radiation-induced improvement of the surface mechanical properties in g-As2S3, the broader distribution of the experimental data was detected for the irradiated sample with radiation-induced oxidized layer, compared to the clean sample without the layer that was removed by washing and polishing.
