Verschleißkennzahlen

Verschleißkennzahlen are a collection of metrics used to quantify and analyze wear processes in materials and components. They provide a standardized way to measure, compare, and predict the extent of degradation due to friction, abrasion, erosion, or other wear mechanisms. These indicators are crucial for assessing the durability, performance, and remaining lifespan of parts in various engineering applications.

Common Verschleißkennzahlen include wear volume, wear depth, wear rate, and specific wear. Wear volume typically refers to the amount of material lost over time, often measured in cubic millimeters or cubic centimeters. Wear depth, on the other hand, quantifies the reduction in thickness of a component. The wear rate is the change in wear volume or depth per unit of time or sliding distance, indicating how quickly wear is progressing. Specific wear is often defined as the wear volume per unit of applied load and sliding distance, allowing for normalization and comparison across different testing conditions.

The calculation and interpretation of Verschleißkennzahlen are essential for material selection, design optimization, and maintenance scheduling. By monitoring these values, engineers can identify potential failure points, extend the service life of equipment, and reduce operational costs associated with premature component replacement and downtime. They are fundamental to tribology, the science of friction, wear, and lubrication.
