Hot Erosion of Glass.

Abstract

In this paper the effect of plastic flow on the erosion of soda-lime-silicate glass at elevated temperatures is investigated. Although the erosion of glass at 500 C and 600 C is still basically a brittle process, viscous relaxation of glass during impact reduces the driving force for fracture and thus the size of the chips that are formed during erosion. As a result, the erosion rate of glass at 500 C or 600 C is decreased by a factor of 2 compared to that measured at room temperature. To completely eliminate fracture during erosion, a temperature of approximately 800 C is estimated for soda-lime-silicate glass. (Author)
