Multi-method characterization of soda-lime glass corrosion : Part 1. Analysis techniques and corrosion in liquid water Report of the International Commission on Glass (ICG) Subcommittee of Technical Committee 19 "Glass Surface Diagnostics"

Abstract

Corroded soda-lime float glass surfaces prepared in water (room temperature and 60 °C) or air (relative humidity of 95 %, 60 °C) for different times are invesdgated by means of SIMS, SNMS, XPS, NRA, ERD, RBS, GIXR, AFM, SEM, light microscopy and scratch testing. The corrosion effects are studied for as-received and cleaned glass surfaces. Changes in the dement concentration in the glass interfaces with the immersion time in water are described. They are combined with variations in density of the surface layer which exhibits plastic deformation behaviour. Inhomogeneous corrosion leads to changes in the topography and an increase in surface roughness.
