Ceramic Wear Parts are alumina, zirconia, or silicon carbide components installed at abrasive and erosive contact zones. Applications include mining, material handling, conveying, process equipment, and other machinery where hard particles or sliding contact repeatedly act on the working surface.

Core Advantages

Hard Surface for Abrasive Contact

Hardness is specified at HV 1300-1800, with dry-sand wear volume listed at <=0.015 cc. The hard ceramic face is intended for continuous particle sliding or abrasive rubbing, where retaining the original working geometry is important.

Strength Across Different Wear Duties

Across the available ceramic systems, flexural strength ranges from 300 to 1200 MPa and density from 3.6 to 6.0 g/cm³. Material selection can be adjusted when abrasion is combined with mechanical loading or erosive particle impact.

Wear Protection in Hot Zones

The listed maximum working temperature reaches 1500°C, depending on the ceramic selected. Wear parts can therefore be used at abrasive contact points near furnaces, heated process lines, or hot material flow where polymeric wear materials are unsuitable.

Customization

Wear-Zone Profile

Flat, curved, and other wear-zone profiles can be made to match the actual contact area in the equipment.

Mounting Features

Holes, slots, chamfers, and mounting details can be set to the carrier or equipment interface.

Contact-Surface Finishing

Selected wear and mating surfaces can receive grinding, polishing, drilling, slotting, or edge finishing.

Quality Control

Material batches are identified before forming. Green and sintered parts are checked for density-related defects, cracks, distortion, and edge damage so unsuitable pieces are removed before finishing.

When required by the agreed specification, batch checks can cover density, hardness, and wear performance. Dimensional inspection concentrates on the wear face, mounting features, and fit surfaces that determine how the part seats in the equipment.

Before shipment, finished parts are checked for appearance, accepted dimensions, quantity, and cleanliness. Contact faces and sharp ceramic edges are separated during packing to prevent pieces from striking each other.
