Latest company case about Solving Abrasion & Erosion: A Guide to Wear-Resistant Ceramic Solutions
When Wear is Your Biggest Cost Driver

Abrasion, erosion, and particle impingement destroy equipment in industries like mining, power, cement, and material handling. Wear-resistant ceramics offer the most durable defense.

How Ceramics Combat Wear:

Their extreme hardness (often only second to diamond) directly resists the cutting and gouging action of abrasive particles. Unlike ductile metals that deform, ceramics resist material removal through their strong atomic bonds.

Common Wear-Resistant Ceramic Solutions:
  1. Alumina Tiles & Liners (90-99.5% Al₂O₃): The workhorse for chutes, hoppers, cyclones, and pipe elbows handling abrasive slurries or dry powders.

  2. Zirconia Toughened Alumina (ZTA): Offers better impact resistance alongside high wear resistance for more demanding applications.

  3. Silicon Carbide (SiC): The ultimate choice for extreme abrasion and high-temperature wear, used in burner nozzles, shot blast blades, and seal faces.

Implementation Formats:
  • Bonded Tiles/Plates: Epoxy or cement-based systems for lining large surfaces.

  • Composite Panels: Rubber-ceramic composite for combining impact absorption with wear resistance.

  • Engineered Components: Pumps sleeves, valve seats, and nozzles custom-machined from wear-resistant blanks.

Key Design Principle: Avoid Impact-Only Loads.

While exceptionally hard, standard ceramics are brittle. Proper system design or the use of toughened composites (ZTA, rubber-ceramic) is crucial in high-impact areas.

Result:

Plant operators regularly report a 300-500% increase in service life when replacing steel or polyurethane with engineered ceramic wear components, leading to dramatic reductions in maintenance costs and production interruptions.
