The two surfaces become interlocked due to their crystal structure. Under the tensile force, deformations of the surface can occur, which we perceive as scratches. Galling can be prevented by using sufficient lubricant.

WebOct 30, 2024 · Galling is an issue that occurs with some fasteners. It happens because of the combined effect of adhesion of the metallic surfaces and friction, which occurs during sliding. Because of galling, material from one surface adheres to another, creating a lump. This results in the build-up of excessive lumps that can cause additional galling.
