Wear resistant ceramic parts are high performance ceramic materials commonly used for wear parts in industrial fields. It has extremely high hardness and wear resistance, and can well resist various wear and corrosion.

Common wear resistant ceramic materials are zirconia, alumina, cubic boron nitride, silicon nitride, boron carbide, silicon carbide and so on.

Ceramic material. The main materials used as wear resistant ceramics are oxide ceramics, carbide ceramics and nitride ceramics, etc. Typical wear resistant ceramics are alumina, silicon carbide, silicon nitride and so on.

The wear of wear resistant precision ceramic parts is caused by two aspects, external factors and internal factors. The external factors are mainly friction mode, environment, load, sliding speed, temperature and time.

The internal factors mainly include hardness, strength, toughness, elastic modulus, particle size, porosity, and grain boundary equality. Due to the structure and performance characteristics of precision ceramics themselves, there are many differences with metals.

Wear of wear resistant precision ceramic parts can generally be divided into cutting wear, fatigue wear, adhesive wear, abrasive wear, impact wear and other categories, because the working principle of each wear is not the same, so the wear mechanism is also different, but in practical applications or experiments, they are often not isolated, but related to each other.

Wear resistance of ceramic parts

Ceramic as a very hard material, its wear resistance is also very good. Generally speaking, the hardness of ceramic parts can reach 8-9 in the Mohs hardness scale, which is much higher than the hardness of ordinary metal materials. This makes ceramic parts less prone to deformation or scratches when subjected to wear or friction. In addition, the density of ceramic parts is high, and there are no holes inside the material, which is not easily subjected to external wear, so the wear resistance is also stronger.

Features:

1.Wear resistance: wear resistant ceramic parts after special process treatment, the surface is very smooth, can effectively reduce the adhesion and wear of materials, extend the service life.

2. Impact resistance: wear resistant ceramic parts have good impact resistance, can maintain stable operation under complex working conditions, and are not easy to break.

3. High temperature resistance: wear resistant ceramic parts can work stably in a high temperature environment for a long time without cracks or damage due to temperature changes.

In general, wear resistant ceramic parts have excellent wear resistance, impact resistance and high temperature resistance, which can effectively extend the service life of equipment, reduce maintenance costs and improve production efficiency.

Application field

Wear resistant ceramic parts are widely used in various industries. In the field of mechanical manufacturing, wear resistant ceramic parts are often used as wear protection for parts. For example, in machine tools, ceramic parts are often used as guide bearings, which can reduce wear and friction, improve machining accuracy and life. In addition, wear resistant ceramic parts are also widely used in electronics, chemical industry, metallurgy and other fields, for corrosion resistance, high pressure and other special environment parts manufacturing.
