Surface treatment and corrosion resistance of metal tool forgings

Metal tool forgings have a wide range of applications in industry and daily life, such as pliers, screwdrivers, hammers and so on. These forgings not only need to have certain mechanical properties and durability, but also to be able to maintain stable performance in a variety of complex environments. Therefore, surface treatment and corrosion resistance are crucial for hardware tool forgings.

Surface treatment is an important link to improve the performance and life of metal tool forgings. Common surface treatment methods include heat treatment, electroplating, spraying and so on.

Heat treatment is to change the internal structure and surface properties of metal materials by controlling the heating and cooling process. For metal tool forgings, heat treatment can significantly improve their hardness and wear resistance, while enhancing their corrosion resistance.

Electroplating is the process of depositing a layer of metal or alloy with special properties on a metal surface. By electroplating, a coating with high hardness, high wear resistance and high corrosion resistance can be formed on the surface of hardware tool forgings, thereby improving its service life.

Spraying is a technique in which paint is sprayed onto a metal surface to form a thin film. By spraying, a protective film can be formed on the surface of hardware tool forgings to improve its corrosion resistance and wear resistance. Commonly used spray materials include paint, polyurethane, etc.

Corrosion resistance is an important index of metal tool forgings. When metal tool forgings are used in corrosive environment, their anti-corrosion performance will be severely challenged. In order to evaluate the corrosion resistance of metal tool forgings, a variety of methods and standards can be used for testing and evaluation.

Generally speaking, the methods to evaluate the corrosion resistance of hardware tools include salt spray test, wet heat test, wear test, etc. These tests can simulate a variety of actual use environments and test the resistance of forgings to corrosion, wear and aging.

In practical applications, different types and uses of metal tools forgings have different requirements for corrosion resistance. For example, tools such as pliers need to have good corrosion and wear resistance to maintain their clamping force and durability; Tools such as screwdrivers need to have high hardness and wear resistance to avoid wear and deformation during use.

In short, for hardware tool forgings, surface treatment and corrosion resistance are key factors to ensure its long-term stable use. Through reasonable surface treatment methods and effective anti-corrosion measures, the overall performance and life of metal tool forgings can be improved, maintenance and replacement costs can be reduced, and work efficiency and production efficiency can be improved. Therefore, in the design and production of metal tool forgings, the importance of surface treatment and corrosion resistance should be fully considered to meet the needs of various practical application scenarios.
