The invention provides a sintering process of nickel-coated ceramic, and relates to the technical field of ceramic sintering, and the sintering process comprises the following steps: cleaning and pretreating a ceramic piece; metallization of the ceramic part: preparing molybdenum-manganese metal slurry, and carrying out primary sintering treatment on the ceramic part; the nickel powder raw material is uniformly sprayed to the surface of the metalized ceramic piece in an electrostatic spraying mode, the ceramic body sprayed with the nickel powder is subjected to secondary sintering, and nickel coating treatment is achieved. According to the nickel-coated ceramic sintering process, the common ceramic part is subjected to metallization treatment to enable the common ceramic part to have electrical conductivity, then the surface of the ceramic part is covered with the nickel powder in an electrostatic spraying mode, the sprayed nickel powder can be more uniform through electrostatic spraying, the spraying efficiency is high, the spraying thickness is easy to master, and the nickel powder can be uniformly sprayed on the surface of the ceramic part. And the special-shaped ceramic part machining device further has the beneficial effect of being beneficial to machining of special-shaped ceramic parts and is better in practicability and applicability and wide in market prospect.

本发明提供一种覆镍陶瓷的烧结工艺，涉及陶瓷烧结技术领域，包括以下步骤：对陶瓷件清洗预处理；陶瓷件金属化：制备钼锰金属浆料、对陶瓷件进行一次烧结处理；准备镍粉原料、喷涂覆镍和二次烧结：通过静电喷涂的方式将镍粉原料均匀的喷涂至金属化后的陶瓷件表面，并对喷涂好镍粉的陶瓷体进行二次烧结，实现覆镍处理。本发明的覆镍陶瓷烧结工艺中，先将普通陶瓷件金属化处理，使其具备导电性，然后通过静电喷涂的方式再将镍粉覆盖到陶瓷件表面，静电喷涂能使喷涂的镍粉更为均匀，喷涂效率高，且喷涂的厚度容易掌握，还具有利于对异型陶瓷件进行加工的特点，实用性以及适用性均更好，市场前景广阔。
