Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together. Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing of cryst...
• (a.) Fitted to gall or chafe; vexing; harassing; irritating. • (p. pr. & vb. n.) of Gall
A severe form of adhesive wear which occurs during sliding contact of one surface relative to another. Clumps of one part stick to the mating part and break away from the surface. (Can frequently occur when both the nut and bolt are zinc coated.)
a form of wear in which seizing or tearing of the gear or bearing surface occurs.
Gall'ing adjective Fitted to gall or chafe; vexing; harassing; irritating. -- 
Developing a condition on the rubbing surface of one or both mating parts where excessive friction between high spots results in localized welding with substantial spalling and a further roughening of the surface.The damaging of one or both metallic surfaces by removal of particles from localized areas due to seizure during sliding friction.
A severe form of adhesive wear which occurs during sliding contact of one surface relative to another. Clumps of one part stick to the mating part and break away from the surface. See also: Friction.
Damage to the surfaces of materials sliding in contact with each other, usually caused by the localised welding together of high spots. Common for materials like stainless steel, aluminium alloys and titanium.
The damaging of one or both metallic surfaces by removal of particles from localized areas due to seizure during sliding friction.
causing irritation or annoyance
