wear debris

Wear debris refers to tiny fragments generated when two surfaces in contact slowly degrade or grind against each other over time. These microscopic particles are produced by normal wear or mechanical friction in machines or engines. Accumulation of wear debris can indicate component deterioration and may cause additional damage or failure if not managed. In lubrication systems, capturing and removing wear debris is important to maintain machinery health. Overall, wear debris serves as a marker of wear processes, helping monitor and diagnose the condition of mechanical parts.
