Abrasion Resistance of Materials

Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using an abrasive. Abrasion can be an undesirable effect of exposure to normal use or exposure to the elements. Abrasion resistance is a property which allows a material to resist wear. Materials which are abrasion resistant are useful for situations in which mechanical wearing and damage can occur, including delicate applications such as the construction of space shuttle components. Numerous abrasion resistant products are employed for a variety of applications, including products which can be custom fabricated to meet the needs of specific users. When a product has abrasion resistance, it will resist erosion caused by scraping, rubbing, and other types of mechanical wear. This allows the material to retain its integrity and hold its form. This can be important when the form of a material is critical to its function, as seen when moving parts are carefully machined for maximum efficiency. Abrasion resistant materials can be used for both moving and fixed parts in settings where wearing could become an issue. The resistance of materials and structures to abrasion can be measured by a variety of test methods. These often use a specified abrasive or other controlled means of abrasion. There are a number of ways to make a material resistant to abrasion. One option is to utilize a special coating which creates a hardened layer over the material and resists friction. Some materials are also naturally extremely hard, and are ideal for settings in which abrasion resistance will be desirable. Other materials can be specifically formulated for increased hardness, as seen in plastics facilities which manufacture abrasion resistant plastics with the use of chemicals which harden and strengthen the plastic. Abrasion Resistance of Materials covers on the abrasion characteristics of various materials such as polymer nanocomposites, high performance fabrics, textiles, etc.
