Fracture of the surface layers of soda-lime glass under high-power ion beam irradiation

Resumo

The fracture of the surface layers of soda-lime glass under irradiation with a high-power ion beam of nanosecond duration is investigated. Features of the fracture surface morphology and the depth of spall crack localization in glass are defined. The depth was 10 ± 2 μm after one-time irradiation with a current density of 100 A/cm². With the use of X-ray diffraction analysis the change in the residual tensile stresses in the surface layers of glass after irradiation is evaluated. The possible mechanisms of the observed fractures are discussed.
