Black oxide is a layer of chemically bonded protection added to metal machine parts and other objects to form a layer of protection against corrosion and abrasions. This process will make the metal stronger, less likely to rust, and more reliable in the field, which is something many businesses need from their metal components. If you are unsure whether this is the right option for your unique needs, you can simply take a moment to consider the many unique features associated with this chemical process.
Rust is the number one enemy of any metal considered at risk for corrosion, such as steel, and it can provide a layer of protection against this damaging process. Metal will naturally react with oxygen in the air to cause rust, which will cause the molecules of the metal to break down. This will significantly reduce the structural integrity of the metal over time, and rust can completely eat away at a metal until it is a husk of its original form in a matter of months or years, depending on the circumstances.
However, blacking metal is a process by which you can protect your metals and reduce the chance of rust occurring over time. Depending on the post-treatment applied, you can expect your coating to give resistance equivalent to 144 hours of exposure to salt spray. There are additional applications that are utilised to create extended shelf life for parts that are stored prior to use, and this is also true if you want to prepare them for further surface treatment, such as painting, at a later date.
The layer created by this chemical reaction is so thin that it will absolutely not cause any increase to the metal surface’s dimensions. Unlike painting or plating, this will mean that you can have your metal surfaces blackened without having to accommodate for an increase in size afterward. This should then make it possible for you to provide corrosion protection even for those critical-sized parts that cannot be replaced easily if anything should happen to them.
Oil utilised post-treatment should further increase protection against corrosion, but the oil itself will also aid in the smooth running of mating parts. Blackened metals are less likely to rust and should work together more easily due to the oils utilised to keep everything lubricated. After all, proper lubrication is often the difference between a machine lasting years and a machine falling apart after just a few months of continuous use.
Unsurprisingly, one of the most obvious signs that a piece of metal is blackened is that the surface of the metal has a lustrous black finish. This will add visual appeal and make any treated metal component appear of a higher quality than if you had left it alone to show off its natural surface. Due to the metal also being less likely to rust or corrode over time, it is a great opportunity for you to utilise it in an outdoor setting, especially if you have clients and other regular visitors that will take note of your facility and its appearance.
