Abstract
Glass-lined pressure vessels are widely used in various corrosion conditions because of their excellent corrosion resistance. However, mechanical impact is the most common failure mode of glass linings due to its brittleness. Under the same firing process condition, the impact-resistant properties of glass-lined vessels are largely dependent upon the glaze composition. In this paper, three kinds of glazes were selected to study the impact resistance of the glass lining. Based on the glaze composition analysis, the impact energy measurement and the micromorphology observations of the impact surfaces, the effect of glaze composition on the impact resistance of glass lining was discussed. The results showed that the low content of refractory oxides such as SiO2, ZrO2 and Al2O3 made the glaze easy to melt and with high-temperature fluidity. Therefore, the structure of the glass lining was dense, and glass lining exhibited good resistance to impact.
