How to choose wear abrasion resistant ceramics under heavy impact conditions?

Wear abrasion resistant ceramics are special ceramics whose main function is to prevent wear. However, in many cases, in addition to wear resistance, wear-resistant ceramics also need to be impact-resistant and high-temperature resistant. Especially since the ceramic itself is relatively brittle, it is often used in mines, docks, and steel plants. In environments involving strong impact conditions, you need to pay attention to some skills when choosing wear-resistant ceramics.

1. Choose large pieces of thick porcelain: Small pieces of ceramic are usually spliced together using ceramic adhesive. Under the impact of large pieces of material, this kind of ceramic is easy to crack from the splicing joints, causing the ceramic to break and fall off. Ceramics that are not thick enough can easily be directly smashed or cracked, losing their anti-wear and anti-impact effects. Therefore, try to choose large and thick porcelain in strong impact conditions.

2. If the temperature permits, choose ceramic-rubber two-in-one ceramic: ceramic has weak impact resistance, but rubber has strong impact resistance. The combination of the two complements each other and can solve the problems of wear and impact at the same time. However, it should be noted that rubber cannot withstand high temperatures, so this two-in-one ceramic can only be used in normal temperature environments.

3. Choose ZTA ceramics: What we usually call wear-resistant ceramics refers to alumina ceramics, which have high hardness but are brittle. For this reason, we can improve the ceramic performance by adding other materials to alumina. After continuous research and development and experiments, Chemshun Special Ceramics has developed zirconia alumina composite ceramics, also known as ZTA ceramics. Compared with ordinary alumina ceramics, ZTA ceramics have greatly enhanced toughness and impact resistance, and can operate smoothly in high temperature environments, solving wear and impact problems for many manufacturers.

4. Choose impact-resistant ceramics with bumps: In addition to starting from aspects such as material and thickness, we can also improve its impact resistance by changing the shape of the ceramic, such as creating hemispherical bumps on the surface of the ceramic. This method It can also effectively improve the impact resistance of wear-resistant ceramics.

In short, when choosing abrasion resistant ceramics, these conditions can be selected individually or in combination. We need to make reasonable judgments based on our own needs and actual working conditions.
