Zirconium Oxide Ceramic Shaft for Micro Motor

Zirconium Oxide Ceramic Shaft for Micro Motor

Zirconium oxide (ZrO2) is the first option to make ceramic shafts for micro motors due to their attractive properties, let's make it more specific why zirconia ceramic is a preferred choice for fabricating mini ceramic shafts 

 

1. Excellent wear resistance:  It's 10 times in comparison with stainless steel, therefore, it's a more advanced material for making rotating shafts than stainless steel.

 

2. Extraordinary mechanical strength: The flexural strength is much better than other technical ceramics, it's not easy to crack under a high-speed rotating state.

 

3. Low friction with self-lubrication:  The static friction coefficient of zirconium oxide is 0.2~0.3, but the value of stainless steel is 0.4. The parameter under dynamic state is 0.1.

 

4. Corrosion resistance: ZrO2 ceramic shaft will not react with most strong acids and alkalis except for HF, it's resistant to aging, and never rusts in various high-damp or high-temperature conditions.

 

5. Strong magnetic resistance: zirconia ceramic doesn't have any magnetism, in addition, the thermal expansion coefficient of the ceramic parts is similar to stainless steel, so it can work together with stainless steel very well.   

 

6. High-temperature resistance: zirconium oxide ceramic shafts could withstand high temperatures up to 1000℃, and the mechanical strength would be maintained well under so high heat circumstances.

 

7. High precision dimensions: It's easy to machine without chippings, the dimensions are very precise after machining with ideal consistency of sizes. It would promote the performance further.
