Abrasion
Under Abrasion (also abrasion called) refers to the damage caused by use or transport material loss at the surface of coatings , fabrics, and other substances. The abrasion is caused by mechanical stress, for example friction , and usually produces very small particles ( dust ). In materials science , it is considered wear and tear . Abrasion on car tires is particularly important . According to a study, the resulting microplastic is responsible for 54% of the microplastic in the oceans .
In road construction , the abrasion of the road surface as a result of traffic loads has an important function. When driving on asphalt roads , there is a fine-grained loss of substance on the surface, which leads to the removal of the binding agent and increases the grip of the surface. The impact test also determines the abrasion value, which characterizes the resistance of the aggregate used .
The abrasion resistance , i.e. the resistance to abrasion, can be measured and is standardized for various applications.
