| titleOfInvention | Preparation method of single-phase carborundum solid solution ceramic material |
| abstract | The invention relates to a preparation method of a single-phase carborundum solid solution ceramic material, belonging to the technical field of superhard ceramic materials. The application solves the problems that the prior transition metal carbide and boride have lower solid solubility and are difficult to prepare and obtain the transition metal carbide and boride. The invention adopts a high-energy ball milling mode to prepare the transition metal carbide and the boride into composite powder, and then adopts a discharge plasma sintering or hot-pressing sintering mode to prepare the superhard boride ceramic sintered body. The method can widen the solid solubility limit of carbide in boride by using high-energy ball milling, solves the problem of low solid solubility between transition metal carbide and boride, and obviously improves the strength and hardness of a sintered body by the solid solution strengthening effect between ball-milled composite powder; meanwhile, the high-energy ball milling enables the particle size of the powder to be refined, and the sintering temperature can be effectively reduced. |
