陶瓷材料的性能优越,但是表面质量差,采用短波长激光抛光技术可以有效提高陶瓷材料表面质量。针对紫外激光抛光Al2O3陶瓷过程中可能存在的熔化、汽化、微裂纹、材料的熔融飞溅和光化学作用等不同的作用形式进行了实验研究。通过对抛光后表面形貌特征进行观测,研究了紫外激光抛光Al2O3陶瓷的作用机理,并分析了高能量密度下产生的白色粉末的形貌、附着力、组成成分和主要物相,进一步确定了紫外激光抛光Al2O3陶瓷的作用机制。
The superior performance of ceramic materials, but the surface quality is poor, the use of short-wavelength laser polishing technology can effectively improve the surface quality of ceramic materials. Aiming at the different action forms of melting, vaporization, microcracking, melt-splattering and photochemical action of UV laser polished Al2O3 ceramic, By observing the surface morphology after polishing, the mechanism of UV laser polishing of Al2O3 ceramic was studied. The morphology, adhesion, composition and major phase of white powder produced under high energy density were analyzed. Mechanism of UV Laser Polishing Al2O3 Ceramics.
