Description

Technical Field

[0001] The utility model relates to the technical field of silicon nitride production, in particular to a silicon nitride spray system. Background Art

[0002] Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material characterized by high hardness, inherent lubricity, wear resistance, and atomic crystal properties. It is also resistant to oxidation at high temperatures. It is also highly resistant to thermal shock, capable of being heated in air to over 1000°C, rapidly cooled, and then rapidly heated again without breaking. Because of these excellent properties, silicon nitride ceramics are often used in the manufacture of mechanical components such as bearings, turbine blades, mechanical seals, and permanent molds.

[0003] During the production process of silicon nitride, corresponding chemical reagents need to be sprayed on its surface to provide it with a corresponding structural layer. The existing spraying method is mostly spraying with a spray system. When this method is used, the spraying particles are small and the surface layer formed is relatively smooth. However, when used, it is easy to form blind spots on the surface of silicon nitride, resulting in local raw material shortages during the spraying process of silicon nitride, requiring further raw material replenishment processing, which in turn affects its efficiency.
