Preparation method of diamond-containing tungsten carbide ceramic based on non-contact flash sintering technology
The invention discloses a preparation method of diamond-containing tungsten carbide ceramic based on a non-contact flash burning technology. The method comprises the following steps: uniformly mixingtungsten carbide powder and diamond particles which are used as raw materials in a fuming cupboard to obtain a tungsten carbide ceramic mixture with the diamond mass fraction ranging from 5% to 90%, dropwise adding an adhesive solution until the ceramic mixture is completely soaked, after the sample becomes a block and the adhesive solution is completely volatilized, putting the obtained block sample into a mold ring, and pressing the sample into a cylindrical shape by hands or in a cold pressing manner to ensure that under a condition that the maximum pressure does not exceed 100 kg, a ceramic green body is not loosened after being taken out; and putting the prepared ceramic green body into a copper crucible on the surface of an electrode, starting an industrial water cooling machine, andcarrying out flash burning by utilizing an argon arc welding machine under the protection of high-purity argon.
基于非接触式闪烧技术的含有金刚石的碳化钨陶瓷的制备方法,包括以下过程:以碳化钨粉末和金刚石颗粒为原料,在通风橱中将其混合均匀,得到金刚石质量分数在5%‑90%之间的碳化钨陶瓷混合物,滴加胶黏剂溶液,以至陶瓷混合物完全浸湿,待样品结成块状,胶黏剂溶液完全挥发后,将得到的块状样品置于模具环中,用手或冷压的方式将样品压至圆柱状,最大压力不超过100kg,保证陶瓷坯体取出后不松散;将制备好的陶瓷坯体放在电极表面的铜制坩埚中,开启工业水冷机,利用氩弧焊机在高纯氩气的保护下进行闪烧。
