What Is Micropitting and Why Does It Damage Gear Surfaces?
Micropitting is a form of surface fatigue that occurs on gear teeth under repeated stress, often unnoticed until it causes significant damage. This tiny surface damage results from material fatigue, where the repeated contact stresses weaken the material over time. Surface roughness plays a vital role in micropitting development because rougher surfaces concentrate stress, accelerating fatigue. As the gear teeth experience cyclic loads, microscopic cracks form beneath the surface, gradually growing until they reach the top layer. These small pits may seem insignificant initially but undermine the gear’s integrity, leading to increased friction, wear, and eventually, failure. Understanding how material fatigue and surface roughness contribute to micropitting helps in designing gears that resist this form of surface damage longer.
