Ceramic glaze pinhole repairing method based on femtosecond laser
The invention belongs to the field of ceramic glaze processing, and particularly relates to a ceramic glaze pinhole repairing method based on femtosecond laser. Comprising the following steps: (1) pretreatment: polishing, washing and drying pinholes; (2) heating treatment: heating the ceramic to 200-300 DEG C, keeping the temperature for 10-15 minutes, injecting a borax solution into a pinhole until the pinhole is completely covered with a polished part, and drying; (3) glaze is applied, specifically, the glaze is applied to the pinhole polishing position; and (4) laser scanning is conducted, specifically, laser with the pulse width being 200-500 fs and the laser power being 8-32 W is used for conducting repeated scanning on the pinhole at the scanning speed being 5-100 mm/s, and repairing is achieved. Compared with traditional laser repairing, the femtosecond laser repairing method has the advantages of being higher in repairing precision, better in repairing effect, small in heat affected zone and high in efficiency when femtosecond laser is used for repairing. The repaired ceramic surface obtained through ultrafast laser scanning is smooth and free of chromatic aberration, no obvious repairing machining trace exists, and the ceramic defect rate can be obviously reduced.
本发明属于陶瓷釉加工领域，具体涉及一种基于飞秒激光的陶瓷釉面针孔修复方法。包括如下步骤：(1)预处理：对针孔处进行打磨、冲洗和干燥处理；(2)加热处理：将陶瓷加热到200～300℃下，保温10～15min后，向针孔处注射硼砂溶液直至完全覆盖针孔打磨处，干燥；(3)施加釉料：对针孔打磨处施加釉料；(4)激光扫描：使用脉宽为200～500fs，激光功率为8～32W的激光以扫描速度5～100mm/s对针孔处进行多次扫描，实现修复。本发明相较于传统激光修复，使用飞秒激光进行修复精度更高、修复效果更佳且具有热影响区小、高效率的特点。经过超快激光扫描得到的修复陶瓷表面光滑无色差，无明显的修复加工痕迹，能够明显减少陶瓷残次率。
