The main functions of Spring Clip Fasteners for blackening include the following:
Improving rust prevention ability: Blackening treatment will form a layer of ferric oxide (black rust) protective film on the surface of Spring Clip Fasteners. This layer of film is strong and stable, and can to some extent inhibit the formation of red rust on the surface of steel (i.e. rust that causes steel corrosion). At the same time, this layer of film has porosity and can be further treated with anti rust oil to prevent water from entering, thereby further improving the anti rust ability.
Improving appearance: Blackening treatment can provide Spring Clip Fasteners with a unique black appearance, which may meet the design requirements of certain specific applications or products.
Improving wear resistance: The Fe3O4 protective film not only has rust prevention function, but also improves the wear resistance of Spring Clip Fasters to a certain extent, making them more durable during use.
Not easy to peel off: Unlike surface treatment processes such as coating and painting, blackening treatment is a surface treatment process that triggers chemical reactions and only changes the surface of the component to a different substance (i.e., a protective film of ferric oxide). This substance has a strong binding force with the substrate, making it difficult to peel off, thus ensuring the long-term stability of Spring Clip Fasteners.
Blackening treatment is a practical and economical surface treatment method for Spring Clip Fasteners, which can significantly improve their rust resistance, wear resistance, and stability.
