Method for preparing high-entropy boron ceramic surface material by vacuum sintering
The invention discloses a method for preparing a high-entropy boron ceramic surface material by vacuum sintering. The material comprises the following components in percentage by weight: 55-78 wt% ofboron carbide powder, 5-9 wt% of carbon black powder, 15-17 wt% of a sintering aid and 8-11 wt% of a ceramic additive. The preparation method comprises the following step: carrying out spray granulation on boron carbide powder, carbon black powder, a sintering aid and a ceramic additive to obtain boron carbide granulated powder. The method has the beneficial effect that another key of sintering densification of pressure-free sintered boron carbide ceramic is the sintering densification mechanism of the ceramic. Generally, carbon black is used as a sintering aid for promoting sintering densification of pressure-free sintered boron carbide ceramic. Hot-pressing sintering or spark plasma sintering is adopted, so that the compactness of the boron carbide material is guaranteed, the toughness and strength of the boron carbide material are improved, and a technical foundation is laid for reducing the cost of boron carbide, promoting industrial production and expanding the application range.
本发明公开了一种利用真空烧结制备高熵硼陶瓷表面材料的方法，包括以下重量百分比的各组分：碳化硼粉55‑78wt％，炭黑粉5‑9wt％，烧结助剂15‑17wt％，陶瓷添加剂8‑11wt％，并包括以下步骤：将碳化硼粉、炭黑粉、烧结助剂、陶瓷添加剂经过喷雾造粒后得到碳化硼造粒粉。有益效果是：无压烧结碳化硼陶瓷烧结致密化的另一关键在于陶瓷的烧结致密化机理。一般无压烧结碳化硼陶瓷采用炭黑作为烧结助剂来促进碳化硼陶瓷烧结致密化。采用热压烧结或放电等离子烧结，在保证碳化硼材料致密化的同时提高碳化硼材料的韧性和强度，为碳化硼降低成本推进工业化生产和扩大应用范围奠定了技术基础。
