and Concrete-Making Materials, ASTM STP 169D, Bridgeport, pp. 184-193. [8] Papenfus, N., (2003) Applying Concrete Technology to Abrasion Resistance, Proceedings
Abrasion is the process through which materials lose volume or mass by way of friction. The ability to resist abrasion keeps the material's structure and looks intact. Highly abrasion-resistant materials are desirable for both fixed and moving parts in a setting where wearing is an issue.
Abrasion resistance is the ability of materials to withstand the effects of abrasion, for example: repeated wearing, rubbing, scrapping, etc. Abrasion-resistant materials are handy in inhibiting mechanical wearing and damage. They can be used in the construction of space shuttle components. The abrasion resistance of high …
