Method for strengthening and toughening silicon nitride-based ceramic spring through fibers
The invention discloses a method for strengthening and toughening a silicon nitride-based ceramic spring by using fibers, which belongs to the technical field of ceramic springs, and comprises the following steps: preparing slurry, preparing a spring preform, burning off a mold, and carrying out suspension burning. The preparation of the slurry comprises the following steps: putting ficus pumila seeds and deionized water into a stirrer, stirring at 55-65 DEG C for 5-8 hours, and filtering to obtain pectin; adding a dispersant polyacrylamide into the pectin solution, and uniformly stirring to obtain a pectin premixed solution; adding silicon nitride powder into the pectin premixed solution, and uniformly stirring to obtain a silicon nitride premixed solution; stirring the silicon nitride premixed liquid at 35-45 DEG C, adding citric acid at the same time, and obtaining slurry after the addition is finished; the fiber-toughened silicon nitride-based ceramic spring prepared by the preparation method disclosed by the invention is good in toughness and high in strength and rigidity.
本发明公开了纤维强韧化氮化硅基陶瓷弹簧的方法，属于陶瓷弹簧技术领域，由以下步骤组成：配制料浆，制备弹簧预制体，烧除模具，吊烧烧成；所述配制料浆，将薛荔籽和去离子水放入搅拌机中，在55‑65℃下搅拌5‑8h，过滤得到果胶；将分散剂聚丙烯酰胺加入到果胶溶液中，搅拌均匀，得到果胶预混液；将氮化硅粉加入果胶预混液中，搅拌均匀，得到氮化硅预混液；将氮化硅预混液在35‑45℃下搅拌，同时加入柠檬酸，加入结束后，得到料浆；本发明制备的纤维强韧化氮化硅基陶瓷弹簧的韧性好，强度和刚度高。
