Wear Protection

Wear Protection

Wear protection is critical for keeping the high-cost machines running in all types of industrial applications including food processing, renewable energy, industrial mixing equipment, turbines, pulp and papermills, and many more. Refurbishing and re-applying coatings that provide this wear protection limits down time and keeps high producing machines moving at a steady pace.

What causes wear?

There are a few forms of wear but for industrial applications we are most focused on abrasive wear which is generally caused by hard protrusions or particles moving along a solid facet. Impact wear also may become a factor in certain scenarios but for wear protection coating purposes the ideal characteristics are similar.

Ways to Mitigate Wear:

- Decrease the speed at which the machine is running

- Evaluate and adjust environmental conditions

- Limit the length of exposure

- Design the equipment to optimize geometry

- Increase material hardness

- Wear Protection Coatings

Wear Protection – Coatings

Thermal Sprayed coatings are designed to allow enough ductility to resist impact while providing hardness to mitigate abrasive wear. The wear protection of each coating is dependent on the environment, substrate material, type of wear and hardness of the abrasive material. Wear Protection coatings should be at least harder than the substrate material that is being protected.


Although hardness is a characteristic of an erosion resistant coating, maximum hardness won’t necessarily optimize wear protection. Although ceramics are very hard, they can also be brittle and have minimal impact resistance. There are blended ceramics that can mitigate the low impact resistance and provide great wear protection in many applications.
