Wie hoch ist die Verschleißfestigkeit von 95 % Aluminiumoxidkeramik?


In the industrial field, wear and tear is one of the main factors leading to equipment component failure, shortened lifespan, and increased production costs. Choosing a material with high wear resistance is crucial. 95 Tonerde-Keramik (with Al ₂ O ∝ content ≥ 95%), as an advanced structural ceramic, are renowned for their excellent wear resistance and have become the preferred material for many harsh working conditions.

Excellent Wear Resistance: Principles and Data
The wear resistance of 95 alumina ceramics is not groundless, its root lies in its unique physical and chemical structure.
Extremely high hardness: Its Rockwell hardness (HRA) can reach 80-90, second only to diamond and silicon carbide, far higher than most metals (such as stainless steel with a hardness of about HRC 20-25) and plastics. This means that when abrasives or particles attempt to cut or scratch their surface, ceramics can effectively resist invasion, thereby reducing material loss.
Excellent bulk density and low porosity: Through advanced sintering technology, the 95 ceramic structure is dense, with a bulk density typically ≥ 3.6 g/cm ³ and extremely low open porosity. This dense structure prevents the invasion of wear media and the resulting internal peeling, achieving uniform slow wear rather than rapid brittle collapse.
Stable chemical properties: It has extremely strong corrosion resistance and can withstand acid, alkali, and various chemical solvents. This means that in complex working conditions where corrosion and wear work together, it will not undergo electrochemical corrosion and accelerate wear like metals, and can maintain surface smoothness and integrity for a long time.
Simply put, 95 alumina ceramic is like a ‘silent tough guy’, facing friction, impact, and corrosion with its absolute hardness and density, it can handle them calmly, greatly extending the service life of components.

Product application: What practical problems are solved?
With the above advantages, 95 alumina ceramics are widely used in key parts that require wear resistance, effectively solving pain points in multiple industries:
Mining and coal industries: used as lining plates for cyclones, slurry valves, and conveying pipeline elbows. Solution: Replace traditional manganese steel or polyurethane, solve the problem of high-speed erosion and wear of equipment caused by slurry particles, increase service life by 5-10 times, and reduce downtime and replacement frequency.
Power and steel industries: using fan impellers, dust removal system nozzles, and powder conveying pipelines. Solution: In high-speed dusty flue gas environments, resist the erosion of hard particles such as fly ash, ensure smooth operation of the fan, and reduce energy consumption and maintenance costs.
Cement and powder industry: used as guide vanes for powder selection machines, pneumatic conveying components, and lining for crushers. Problem solving: Prevent wear and tear of equipment caused by high hardness cement clinker and powder, ensuring continuous and stable operation of the production line and product purity.
Mechanical and electronic industries: used as ceramic bearings, sealing rings, and grinding media. Problem solving: Provide self-lubricating and wear-resistant performance in oil-free or high-temperature environments, avoid contaminating workpieces, and improve machining accuracy and equipment reliability.

Product advantages: Why choose 95 alumina ceramics?
Compared with other wear-resistant materials such as metals and polymers, 95 alumina ceramics have comprehensive advantages:

  1. Long service life: The wear resistance is tens or even hundreds of times that of high chromium cast iron, greatly reducing the cost of spare parts replacement and manual maintenance time.
  2. Excellent comprehensive performance: not only wear-resistant, but also has high temperature resistance, corrosion resistance, insulation and other characteristics, suitable for complex environments.
  3. Low operating resistance: The surface is smooth and the friction coefficient is low, which helps to reduce the energy consumption of the equipment during operation.
  4. Environmentally friendly and pollution-free: The material itself is stable, will not rust or produce harmful substances, and meets environmental requirements.

Background of the case: In a large thermal power plant, the induced draft fan blades of its dust removal system have been eroded by high-speed fly ash for a long time. The alloy steel blades originally used need to be repaired or replaced on average every 3 months, resulting in high maintenance costs and severe downtime that affects power generation efficiency.
Solution: We have customized a 95 alumina ceramic fan blade wear-resistant lining plate for it, which is mechanically embedded and fixed with a special dovetail groove structure.
Usage effect: Since installation and operation, it has been continuously working for more than 18 months. After inspection, the wear of the ceramic lining plate is minimal, and the overall life is expected to exceed 36 months. Customer feedback shows that this move saves them over 500000 yuan in direct maintenance costs annually and creates significant indirect economic benefits by reducing unplanned downtime.
