Laser Glazing of Peacock Blue Glaze on Porcelain
Abstract:
This paper presents the study of making peacock blue glaze surface by laser processing. The factors that may affect the quality of the glazed surface, especially the main laser processing parameters, were discussed. The structures and phase transitions of the glaze clad by laser were studied by X-ray diffraction, scanning electron microscopy and metallographic microscope. The color change and thermal stability of the glaze were tested. The results showed that the glazed surface clad by laser with a laser power of 25 W presented good visual characteristics. The color change of these glazed surfaces was inconspicuous with the increase in scanning speed. Several types of microcrystalline were also found in the glazed surface clad with a laser power of 25 W when the scanning speed was 10 mm/min. The glazed surface and the clay body were bonded tightly. The thermal stability of the glazed surfaces with good visual characteristics was also good.
