پوشش سیلیکا سولا ژل برای شیشه های رنگی پوتاسا لیماس: کاربرد و اثر محافظتی

The effect of the sol–gel application was monitored and leaching tests with different times and pH values were performed both on coated and uncoated parts. The protective effect was verified using light microscopy and ToF–SIMS analyses were performed to check the ion migration (e.g. K, Na, Ca and Mg) and the interface between bulk glass and coating. The coating protects the glass from the formation of cracks also after severe treatments that would have caused serious damages on the uncoated glass.
