الملخص

Glass is an important material in the fields of optics, lighting, car, buildings and electronics. Inits major applications, its surface is exposed to a variety of external aggressive conditions(corrosion, chemical reactions and mechanical damages), which lead to a reduction of itsmechanical strength and optical transmission.In the present work, we are interested in the effect of a chemical treatment by HF acid attackon the various characteristics of Soda lime, glass eroded by sandblasting.This technique is considered as a glass mechanical strengthening method that improves itsglass lifetime. We studied the evolution of the glass properties (optical transmission,mechanical strength) in function of the attack duration by HF.To explain the mechanisms of the HF chemical attack, we carried out Vickers indentationsunder various loads which are subjected to various attack duration. The observations of theindentation imprints show the surface cracks blunt gradually with the HF attack duration andtend to form a cellular morphology.
