Preparation method of ceramic heating body and ceramic heating body
The invention relates to a preparation method of a ceramic heating element and the ceramic heating element, and the preparation method of the ceramic heating element comprises the following steps: preparing a metal diaphragm by a tape casting method; porous ceramics with different heat conductivity coefficients are provided; laying the metal diaphragm on at least one surface of the porous ceramic to obtain a ceramic heating body blank; a pattern program is imported into selective laser equipment in advance, then the ceramic heating body blank is placed in laser equipment protected by nitrogen atmosphere, heating film laser sintering is carried out, a heating film with a preset pattern is formed on the surface of the porous ceramic, and the ceramic heating body is obtained. Metal ions in the porous ceramic and the metal membrane are subjected to state treatment by utilizing a high-energy laser beam, so that the porous ceramic and the metal membrane are firmly combined, the heating membrane is good in consistency and is firmly combined with the ceramic, the part, without the heating membrane, of the metal membrane is automatically separated, traditional procedures such as printing, drying and sintering are not needed, the product preparation speed is high, and the energy consumption utilization rate is high.
本发明涉及一种陶瓷发热体的制备方法及陶瓷发热体，陶瓷发热体的制备方法，包括以下步骤：流延法制备金属膜片；提供不同导热系数多孔陶瓷；将所述金属膜片铺设于所述多孔陶瓷的至少一面，获得陶瓷发热体坯体；预先将图形程序导入选择性激光设备中，然后将所述陶瓷发热体坯体置于氮气气氛保护的激光设备，进行发热膜激光烧结，在所述多孔陶瓷的表面形成预设图形的发热膜，以获得陶瓷发热体。利用高能激光束将多孔陶瓷和金属膜片中的金属离子态化，使二者牢固结合，发热膜一致度好与陶瓷结合牢固，没有金属膜片没有形成发热膜的部分自动脱离，不需要印刷、烘干、烧结等传统工序，产品制备速度快，能耗利用率高。
