Characteristics and strengthening requirements of alumina ceramics
Alumina ceramics must be familiar to everyone, and they are widely used in our daily life. Here, I will explain the product characteristics of alumina ceramics for strengthening requirements, and help you understand alumina ceramics.
1. Strengthening requirements of alumina ceramics
do you know? Nowadays people use alumina ceramics very extensively. Now a popular technique is called alumina ceramic strengthening process. This is a new type of operation process. It mainly uses a layer of film on the surface of alumina ceramics. It is in the form of vacuum coating, and can also be in the form of electronic or water gun coating. Coating a layer of thin film on alumina ceramic can play a certain protective role, strengthen the performance of the ceramic, and make the hardness and strength increase obviously.
2, the characteristics of alumina ceramics
a. High hardness
Determined by authoritative research, its Rockwell hardness is HRA80-90, hardness is inferior to diamond only, far exceeding the wear resistance of wear-resistant steel and stainless steel.
b. Excellent wear resistance
The wear resistance of alumina ceramics is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. Generally under the same working conditions, alumina ceramics can at least extend the service life of the equipment by more than ten times.
c. Light weight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
Alumina ceramics have very good wear resistance. The wear resistance is far more than that of steel. The strong hardness determines its service life. It can be used for more than ten times longer than ordinary ceramics. Its hardness is comparable to diamond. Although it is a little bit worse, it is superior to stainless steel and wear-resistant steel. Although it has high hardness and strong wear resistance, it is very light, not heavy at all, and it is more convenient to operate.
