Injection forming method of molybdenum disilicide ceramic
The invention relates to the technical field of powder metallurgy, in particular to an injection forming method of a molybdenum disilicide ceramic product. The injection forming method comprises the following steps that an adhesive and molybdenum disilicide powder are mixed on a mixing mill according to the ratio of (22g-30g):100g and then are granulated, injection forming is conducted on obtainedparticles to obtain a green body, catalytic degreasing is conducted to obtain a degreased blank, and finally, the degreased blank is subjected to reductive sintering to obtain the molybdenum disilicide ceramic product. According to the injection forming method, a near-net forming technology formed by combining a traditional powder metallurgy technology and a plastic injection forming technology is utilized, the intermediate machining link of the traditional powder metallurgy technology is omitted, raw materials are saved, meanwhile, the high-efficiency and low-cost automatic continuous production is realized, the production and machining cost is reduced, the limitation of a traditional metal powder die pressing forming process on the product shape is further broken through, and the molybdenum disilicide ceramic product with complex shape, small size and high dimensional precision can be integrally formed and prepared.
本发明涉及粉末冶金技术领域，具体涉及一种二硅化钼陶瓷制品的注射成形方法，将粘结剂与二硅化钼粉末按照22g～30g:100g的比例在混炼机上混炼后制粒，将得到的颗粒注射成形得到生坯，再催化脱脂得到脱脂坯，最后将脱脂坯进行还原烧结得到二硅化钼陶瓷制品，本发明利用传统粉末冶金技术与塑料注射成形工艺相结合形成的一种近净成形技术，不但省去了传统粉末冶金工艺的中间机械加工环节，节省原材料的同时，实现了高效率、低成本的自动连续生产，降低了生产加工成本，还突破了传统金属粉末模压成形工艺在产品形状上的限制，可以一体成型制备形状复杂、体积小、尺寸精度高的二硅化钼陶瓷制品。
