Factors affecting the wear resistance of ceramics 

According to ceramics composition,wear-resistant ceramic can be classified into alumina ceramics, zirconia ceramics and silicon carbide ceramics, silicon nitride ceramic. and the cost for them is different , which much affect market promotion and application 

The main index of abrasion ceramics liner is wear resistance properties and strength,

No matter you are ceramic liner manufacturer, or abrasive linings distributor, ceramic project users, It is much useful for us to know the factors affecting wear restance.

Chemshun as alumina ceramic liner factory, have full experience of producing 92% 95% Al2O3 wear resistant liners which used in hopper;chute;bunker;pulley laggings;ball mill;cyclone;bend pipe;convey belt; Distribution Box; Ejectors; Fans; Feeders; Hopper; Launders; Manifolds; Mills; Orifice; Pipes; Pipe Bends; Pipe fitting; Pulley lagging; Silos; Splitter Boxes; Spoons; Square Bends; Square to Round; Tanks; Troughs; Transfer points; T-Pieces; Y-Pieces etc

Factors that affect strength wear-resisting ceramics include the following:

1--- Raw material particle size:ceramic material prepared well only when grinding into  fineness,more delicate the prepared material is , the colour and lustre of the finished product can be ensured, the density will be more higher, wear resistant property will better.

2----sintering temperature and stability : the best sintering temperature is different for different ceramic materials. if temperature is too high ,  ceramic molding time is too short, ceramic is relatively lack of toughness.Temperature is too low, not burn through ceramic, internal and external finished ceramic quality is different.Now the  fire ceramic tunnel kiln and shuttle kiln is commonly used in the majority, the temperature at the ends of kiln is not same, so production will undertake collocation according to the actual situation of their products.

3----- Porosity: porosity increase inevitably leads to reduce the high temperature strength.And at high temperature, due to reasons such as passivation of the crack tip, the ceramic material for cracks and the sensitivity of the micro defects are low, this is mainly embodied in the impact on the fracture toughness.

The influencing factors of wear resistant ceramic more than above, particle erosion intensity, and the characteristics of corrosion medium, hard material factors such as the size of the collision incident Angle, anyhow wear-resisting ceramics performance is affected by these factors, and only these therefore affect the least amount of time, the performance characteristics of wear-resisting ceramics can play a maximum

Chemshun keep studying alumina ceramic liners , from raw materials to fnished ceramics, hope to improve the wear resistant property perfomance for customer wear
