摘要
将灰色理论与均匀设计应用于研究SiO2-Al2O3-CaO-MgO-K2O-F-体系微晶玻璃中氧化物组分与可切削性能的关系.均匀设计用于安排试验,用灰色关联分析来考查各氧化物组分对材料可切削性的影响.结果表明:K2O的引入能促使云母基本结构基团[AlSiO3]的形成,K2O和Al2O3的共同引入是生成云母相的必要条件;CaO和MgO可以显著降低玻璃的高温粘度,但含量应控制在适宜的范围.均匀设计用于实验设计可使试验工作量显著降低;而用灰色理论处理实验数据可以定性分析影响云母相生成的主次因素.
Grey theory and uniform design were applied to study the relationship between the machinability and compositions of SiO_2-Al_2O_3-CaO-MgO-K_2O-F^-glass-ceramics. Experiments were performed with uniform design, and the grey relational analysis was employed to investigate the influence of compositions on the machinability of glass-ceramics. The results showed that K_2O could promote the formation of basic structure group of mica, and the combination of K_2O and Al_2O_3 was essential for the formation of mica crystallization. CaO and MgO could considerably decrease the viscosity of glass at high temperatures, but they had to be controlled within certain contents for crystallization. Uniform design could reduce more experimental work than traditional methods. The application of grey theory to the analysis of experimental results made it possible to identify qualitatively the major and minor factors for the formation of mica.
