In Saharan regions, the sandstorm has an negativeinfluence not only on the rural and urban environment,but also on the erosion of brittle materials, particularlyglass products (home windows’ glass, windshields andheadlights of vehicles, solar panels protective glass...),or coated glass with thin layers (functional glasses). Thisinfluence often results in a deterioration of the surfaceby sand particles impacts. In fact, particles impacts onthe glass surface generate various superficial defects(microcracks, craters and scaling) that scatter the incidentlight, and thereby reduces the optical transmission.Furthermore, the impact points of the damaged glassare privileged sites of sand dust deposits that affectin particular the photovoltaic efficiency of solar panels,visibility through windshields of vehicles [1]... Accordingto literature [2,3], the erosion process in glasses isconsidered as elastic-plastic. Imprints formed at the impactsites are accompanied by a network of cracks caused by theimpact force. This results in a gradual weight loss duringerosion. In the case of eroding sharp particles, there isa formation and growth of radial cracks on the surface.Lateral cracks that form at the base of the contact areaconverge to the outside almost parallely to the surface. Ingeneral, lateral cracks are responsible for the mass loss byscaling mechanism, while radial cracks are the cause ofthe mechanical resistance deterioration [4]. Hutchings [5]and other authors have reported that the erosion of brittlematerials is affected by many factors:- Properties of the incident particles (size, shape, density,hardness, fracture toughness);- Properties of target materials (hardness, fracturetoughness and surface state),- Test conditions (impact velocity, impact angle andtemperature).In this work, the influence of two test parameters (fluxvelocity and impact angle) on the evolution of the surfacedefects generated by sandblasting is presented. A statisticalstudy is applied on the obtained defects sizes distribution.
