Definition - What does Abrasion Resistant mean?
Abrasion resistant refers to the ability of materials or structures to withstand any method of wearing down or rubbing away by means of friction. This ability helps the material maintain its original structure and appearance, and resist mechanical wear. Abrasion resistant materials are useful for both parts that move and fixed parts in settings where wear is an issue.
The abrasion resistance of materials and structures is evaluated by a variety of test methods such as abrasion scrub testers.
Corrosionpedia explains Abrasion Resistant
Abrasion resistance is a property that allows a material to resist wear. The abrasion resistance of a material helps it to withstand mechanical action and prevent the removal of material from its surface. This allows the material to retain its integrity and form. This is important when the form of a material is critical to its function, such as when moving parts have been carefully machined for maximum efficiency.
Abrasion resistance can be imparted through:
- Using proper lubricants
- Covering items with an abrasion resistant material or coating
- Controlling the cause of abrasion
In rubber, there are two types of abrasion:
- Sliding – the passing of an adjacent surface across the rubber surface
- Impingement – wearing of the rubber exemplified by small particles (e.g., sand) hitting the surface
When the rubber cannot withstand localized friction forces, abrasion and wear occurs.
High-performance concrete has high abrasion resistance because it contains silica-fume, making it useful for concrete pavement overlays where heavy or abrasive traffic frequently occurs.
