High-entropy boride ceramic pellet as well as preparation method and application thereof
The invention discloses a high-entropy boride ceramic ball as well as a preparation method and application thereof. The ceramic ball is prepared from the following components in parts by weight: 30 to 65 parts of boride powder, 0.4 to 1.5 parts of an adhesive, 0.1 to 1.5 parts of a pH regulator, 0.1 to 1.5 parts of a defoaming agent and 0.6 to 1.5 parts of a dispersing agent. The sphericity degree of the ceramic ball is not less than 90%, the ball diameter range is 30-80 [mu] m, and the content of impurity oxygen and the content of impurity carbon in the ceramic ball are both lower than 1 wt%. The ceramic pellet provided by the invention can be suitable for preparing a high-entropy boride ceramic coating by a thermal spraying process.
本发明公开一种高熵硼化物陶瓷小球及其制备方法和应用，所述陶瓷球由包括如下重量份的组分制备得到：硼化物粉体30‑65份、粘接剂0.4‑1.5份、pH调节剂0.1‑1.5份、消泡剂0.1‑1.5份、分散剂0.6‑1.5份。本发明的陶瓷小球的球形度不小于90％，球径范围为30～80μm，且陶瓷小球中杂质氧和杂质碳的含量均低于1wt％。本发明的陶瓷小球可适用于热喷涂工艺制备高熵硼化物陶瓷涂层。
