WebFeb 3, 2024 · Galling — also called cold-welding or cold-fusing — happens when two fastener surfaces are placed under heavy pressure and lock together. Thread galling can occur when pressure and friction cause the bolt threads to seize to the threads of a nut or a tapped hole. Essentially, it’s a rapid form of wear and tear. WebOf the metallic materials, cobalt-based alloys are generally regarded as the most resistant to sliding wear at high loads, in the absence of lubrication. Under such conditions, a form of damage known as “galling” is common; this is thought to occur by gross plastic deformation, atomic bonding (or cold welding), then fracture on one or both ...

WebGalling, or cold welding as it is sometimes referred to as, is a form of severe adhesive wear. Adhesive wear occurs between two metal surfaces that are in relative motion to each other and under sufficient load to permit the transfers of material between themselves. This is a solid-phase welding process.
