摘要
研究了适合于Be O高导热陶瓷的"钨锰法"金属化浆料配方和批产工艺,并利用扫描电镜等手段对金属化层的表面形貌进行表征,重点探讨了金属化浆料中活化剂占比、金属化最高烧结温度以及浆料细度对金属化层表面形貌和结合强度的影响和机理。结果表明:当活化剂质量分数为11%,最高烧结温度为1450℃,浆料细度控制在12μm时,Be O高导热陶瓷金属化层表面形貌和结合强度最优。
The formulation and batch producing process of‘tungsten and manganese’metallized paste used in the BeO highthermal conductivity ceramics were studied.The surface topography of metallization layer was tested by scanning electron microscope.The effects and mechanism of the proportion of activator in the metallized slurry,the highest sintering temperature of metallization and the fineness of the slurry on the surface morphology and bonding strength of the metallization layer were discussed.The test result indicates that the best surface morphology and bonding strength of BeO highthermal conductivity ceramics metallization layer are gotten when the mass fraction of the activator is11%,the highest sintering temperature is1450℃and the fineness of the paste is controlled at12μm.
