Multi-method characterization of soda-lime glas corrosion Part 2.Corrosion in humidity

摘要

As-received and cleaned soda-lime glass surfaces corroded in high relative humidity of 95% at a temerature of 60degC for times up to one week are investigated by means of TOF-SIMS,SNMS,XPS,NRA,ERD,RBS,GIXR,AFM,SEM and optical microscopy.Distinct differences in the corrosion behavior are observed for as-received and cleaned glass surfaces.Changesin element concentation in the glassinter face and in the topography of the glass surfaces are desribed for different exposure times in humidity.They are combined with variations in density of the modified surface layer.Cleaning before the corrosion treatment drastically reeuces degradation;cleaning after the corrosion treatment can restore the surface.
