Vulcabrix® ZTA

The zirconia toughened alumina tiles used to create Vulcabrix ZTA ceramic composite gives these wear liners increased resistance to cracking when compared to conventional alumina tile based liners. The ZTA liners also offer improvements in weight management due to their lower density than metallic liners.

As well as welded studs for quick and easy attachment, Vulcabrix ZTA offers custom shapes, bevels and edge protection.

An alumina powder is blended with zirconia powder at a precise ratio before the tile is pressed into the desired shape. The zirconia addition gives the tile increased impact resistance when compared to typical alumina tiles. After pressing the powder into a mould, sintering at 1500-1600°C binds the powder particles together creating a solid tile. The tiles are then attached to a steel backing plate using controlled heating and pressing, rubber vulcanization process cycle. The rubber provides cushioning to the tiles whilst allowing for the flexibility of attachment methods to the backing plate. The liner is then ready for post-processing and use in extremely abrasive environments involving moderate to high impact.
