Galling failure
/ˈɡælɪŋ ˈfeɪljər/
A galling failure is a mechanical breakdown caused by adhesive wear when metal surfaces seize together under friction.
Examples
- Proper surface coating can significantly reduce the chance of galling failure.
- If you tighten stainless steel threads too fast, you risk galling failure.
- The report identified repeated galling failure in the gearbox components.
- The bolt suffered a galling failure during assembly due to insufficient lubrication.
- Engineers redesigned the joint to prevent galling failures in high-torque applications.
