Micro pitting : ウィキペディア英語版 | Micro pitting
Micro pitting is a fatigue failure of the surface of a material commonly seen in rolling bearings and gears. It is also known as grey staining, micro spalling or frosting. ==Pitting and micropitting== The difference between pitting corrosion and micropitting is the size of the pits after surface fatigue. Pits formed by micropitting are approximately 10-20 μm in depth, and micropitted metal often has a frosted or gray appearance. Normal pitting creates larger and more visible pits. Micropits are originated from the local contact of asperities produced by improper lubrication.
