What is Anti-Galling?
Anti-galling is a preventive measure taken to avoid the phenomenon of galling, a type of adhesive wear where two metal surfaces in contact freeze or stick together due to friction and pressure. Anti-galling methods are designed to reduce friction, enhance surface hardness, and minimize the likelihood of metal-to-metal contact.

Benefits of the Anti-Galling Process
Some of the benefits of the anti-galling process include the following:
Increased service life of parts and equipment
Reduced maintenance and repair costs
Prevention of parts from locking or becoming loose
Enhanced reliability in critical industries (medical, oil and gas, and aerospace industries)
The main reason for using the anti-galling process is to increase reliability, and this process is often carried out with that goal in mind. For this reason, it is commonly used in most critical industries to also extend the service life of components.

Methods to Prevent Galling
The following methods can prevent the phenomenon of galling and reduce wear and galling on components. These methods are applied in various industries, and the best method can be selected based on the functionality of the devices. The process is carried out based on its feasibility and requires thorough and precise examination.
Choosing the Right Metal: As mentioned earlier, galling refers to the transfer of particles from one part to another. The harder the selected metal, the less likely galling will occur between metals. Steel alloys with nickel compositions and hardened steel can prevent galling.
Proper Coating : Using coating methods that increase the hardness of metals is an effective option to prevent galling. For example, hard chrome plating can enhance the surface resistance of parts and prevent galling.
Use of Lubricants : Various lubricants are used to reduce friction and stress between components, thereby preventing galling. For instance, greases and oils can be applied to different parts, or anti-seize compounds (containing copper, graphite, and molybdenum disulfide) can be used.
Optimizing Mechanical Design of Parts : Sometimes, adjusting proportions and quantities can prevent the occurrence of galling in parts.
Applications of Anti-Galling
Industries that use anti-galling for their equipment:
Oil and Gas Industry: Bolts, fasteners, and valves in the oil and gas sector use anti-galling to increase their service life and enhance reliability. This helps reduce maintenance and repair costs for the equipment.
Automotive and Heavy Machinery Manufacturing: Some vehicle components that are exposed to pressure and constant contact are treated with anti-galling to increase their resistance and prevent part wear due to friction and contact. Key components in vehicles, such as power transmission parts, including bearings, bushings, and other elements, benefit from this treatment.
Aerospace Industry: Aircraft components require high precision and advanced technology in their design and construction. Anti-galling is applied in aircraft engine repairs, ensuring compliance with global aircraft manufacturing standards.
Medical Equipment: Anti-galling is used in the manufacture of certain medical tools, such as surgical instruments and implants, to increase the strength and quality of the components.
Infrastructure Projects: In the construction of high-resistance civil engineering projects, such as bridges, anti-galling-treated products are used. This increases the durability, strength, and lifespan of the constructed structures.
