| titleOfInvention | Wear-resistant silicon nitride material for papermaking dewatering panel and preparation method thereof |
| abstract | The wear-resistant silicon nitride material for the papermaking dewatering panel comprises a silicon nitride main material and a total sintering aid, wherein the total sintering aid accounts for less than 15 wt% of the total weight, and is characterized in that the wear-resistant silicon nitride material is prepared from the following materials in percentage by weight: si3N 4: 85-94 wt%; Y2O 3: 1-6 wt%; al2O 3: 2-8 wt%; co: 0.1-1 wt%; WC: 0.5 to 4 wt%. According to the invention, by adding WC and Co, the density of the prepared material reaches 99.7%, the Vickers hardness reaches 1700Hv, and the hardness is improved by 20% compared with that of the conventional formula; the wear resistance of the ceramic material is improved by 4 times compared with the traditional material and 30 percent compared with the wear resistance of the silicon nitride material with the conventional formula, and the ceramic material can fully meet the performance requirements of the ceramic material of the papermaking dewatering panel. |
