Key Locking Threaded inserts are commonly used in various industries to strengthen and reinforce materials that undergo stress and pressure. However, just installing an insert isn't enough to ensure its longevity and durability. It needs to have a proper surface treatment, such as galvanization of the threaded inserts.
Galvanization is a process that involves the application of a thin layer of zinc over a base metal. This process is used to enhance the corrosion resistance of metals, which ultimately increases their lifespan and longevity. Zinc is a highly corrosion-resistant material, which is why it is used for galvanization.
When it comes to threaded inserts, galvanization is especially important because these metal devices are typically used in harsh environments, and are exposed to various factors that may cause corrosion, such as moisture, chemicals, and abrasion. Without proper surface treatment, the insert may become weak and rusted, which would eventually lead to failure of the assembly.
This is where galvanization plays a crucial role. By applying a thin layer of zinc over the insert, the galvanic coating creates a barrier between the insert and the environment, thus protecting the insert from corrosion. Additionally, the zinc layer also serves as a sacrificial anode, which means that it will corrode first before the metal underneath it. As a result, the base metal will remain protected.
There are various methods of galvanization, including electroplating, hot-dip galvanization, and mechanical plating. Each of these methods has its own advantages and disadvantages, and the most appropriate method will depend on the type of insert, the environment it will be exposed to, and the desired level of protection.
In summary, galvanization is a crucial process in ensuring the longevity and durability of threaded inserts. By applying a thin layer of zinc over the base metal, galvanizing protects the insert from corrosion and creates a sacrificial anode that further enhances its protection. Therefore, it's essential to choose the right surface treatment method to ensure the success and longevity of your insert applications.
