Abstract

In this work, we experimentally study the features of laser drilling of composite highly porous ceramics consisting of aluminosilicates, glass and a small addition of polystyrene (EPS). It was found that the formation of a liquid phase can contribute to the strengthening of ceramics. A list of factors that determine the dynamics of hole formation is proposed. These include not only the processes of heating, melting, ablation, and ejection, well known previously for metals and dense ceramics, but also a number of other specific processes: (a) boiling of the component of the mixture with the lowest temperature of thermal decomposition and its escape from the affected zone; (b) a melt of less volatile components; (c) sealing the ceramics adjacent to the walls due to the mechanical sealing effect of ablative pressure; (c) glass transition of the liquid phase upon cooling after the end of irradiation.
