How does galling occur

WebGalling, which can take place on several metal types, refers to a type of wear that causes a metal to adhere to another different metal when they’re in contact. This often results in the metal separating from its original … WebGalling occurs when two metals are in sliding contact. 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. Certain alloys, such as brass or bronze, are also more resistant to ...
