impingement wear
Quick Summary
Impingement wear is a type of tribological wear that occurs when particles forcefully collide with and erode a surface. This is a significant wear mechanism in industries like mineral handling.1
In contrast, rubbing wear happens when two loaded surfaces slide against each other. Ceramics are often used to resist these wear types due to their hardness and strength, stemming from strong chemical bonds.1
Alumina is a common, cost-effective ceramic used for wear resistance, though it can be prone to grain pullout, which exacerbates impingement wear. More advanced ceramics, like transformation-toughened zirconia, offer improved toughness and wear resistance by inducing compressive stress on the surface during wear. These materials are crucial in various industrial applications, from mineral processing to manufacturing.1
