Method for preparing silicon nitride ceramic based on selective laser sintering
The invention provides a method for preparing silicon nitride ceramic based on selective laser sintering, and relates to the technical field of laser processing and ceramic preparation, and the method comprises the following steps: mixing silicon nitride powder, a sintering aid and a binder into a stirring device in proportion to obtain silicon nitride ceramic slurry; coating the silicon nitride ceramic slurry on a base material to form a to-be-sintered layer, and performing selective sintering on the to-be-sintered layer by using a laser device; and repeating the operation until the silicon nitride ceramic with the required shape and thickness is obtained. By arranging and utilizing the laser device, the technical problems of long production period, high production cost, low material density and the like of the traditional silicon nitride ceramic preparation method, such as hot pressing sintering, pressureless sintering and the like, proposed by the background technology are effectively improved.
本发明提供了一种基于激光选区烧结制备氮化硅陶瓷的方法，涉及激光加工和陶瓷制备技术领域，包括：将氮化硅粉末、烧结助剂和粘结剂按比例混合到搅拌装置中，得到氮化硅陶瓷浆料；将氮化硅陶瓷浆料涂抹在基材上，形成待烧结层，利用激光装置对待烧结层进行选区烧结；重复上述操作，直至得到所需形状与厚度的氮化硅陶瓷。通过设置利用激光装置，有效的改善了背景技术提出的：传统的氮化硅陶瓷制备方法，如热压烧结、无压烧结等，存在生产周期长、生产成本高、材料致密度低等的技术问题。
