Silicon Nitride Ceramic Rods Structural Partsmerits
With the advantages of high strength, high hardness, wear resistance, high temperature resistance, corrosion resistance and light weight, silicon nitride ceramic rod structure parts are gradually replacing the traditional metal materials and becoming the basic parts in high-end equipment manufacturing. Silicon nitride ceramic rod structure parts with low coefficient of thermal expansion, high thermal conductivity, so its thermal shock resistance is excellent. Within 1000 ℃ temperature, silicon nitride ceramics have high strength and impact resistance.
Description
Advantages of Silicon Nitride Ceramic Rod Structures
Silicon nitride has high mechanical strength and hardness, and can withstand large axial loads, radial pressure and repeated impact loads. Compared with traditional metal shaft parts, its wear resistance is more prominent, and it is less prone to wear and dimensional drift in long-term use. Moreover, it has excellent thermal shock resistance and will not rupture when heated up to 1000°C in air and then rapidly cooled.
- rotating component
- Load transmission components
- Precision guide shafts
- Wear-resistant shaft pins for automation equipment
Applications of Silicon Nitride Ceramics
Silicon nitride ceramics have excellent mechanical, thermal and electrical properties. It is also one of the most thermodynamically stable high hardness industrial ceramic materials. It is ideal for bearing parts, especially those that need to work at high temperatures and pressures. Therefore, silicon nitride ceramic products are ideal for many industries, such as:
- Rotary ball and roller bearings
- Cutting Tools
- Engine components: valves, rocker gaskets, sealing surfaces
- Induction heating coil holder
- Turbine blades, wheel blades, buckets
- Welding and brazing fixtures
- Heating Element Assemblies
- crucible
Basic Properties of Silicon Nitride Ceramics
