Metal Blackening: The New Age of Protection and Visual Appeal
Not too long ago, almost every home featured what we now call “tacky wallpaper.” Soon after that, shag carpets were all the rage. Fast-forward a few more years, and the vast majority of homeowners were covering their furniture with a strange plastic coating. These various fads have come and gone over the passage of time, with bigger and better solutions taking their place every few years. However, it is important to note that as technology and science continue to expand, mankind is now able to create lasting solutions that can actually withstand the test of time. One of these advancements is the concept of black oxide, which is more commonly referred to as “metal blackening.” This brief article will review this modern technique to protecting metal-based accoutrements and enhancing their aesthetic appeal.
How Does Metal Blackening Work?
At its core, metal blackening is essentially the creation of a conversion coating for ferrous metallic surfaces, such as zinc, copper, steel, silver solder, etc. Contrary to popular belief, this conversion coating is not a simple spray-on or paint-on product, as it actually alters the chemical makeup of the substrate’s surface.
As the metal blackening process begins, a chemical reaction takes place on the item’s surface. The blackening solution and its oxidizing salts combine with the ferrous metal to create black iron oxide, which is also known as magnetite (Fe3O4). The resulting magnetite is, essentially, a brand new seal on the metal and it is firmly fused in place.
Why is Metal Blackening Important?
If you establish a relationship with a reputable metal blackening specialist, such as Blackfast, you’ll quickly see why this technique is so beneficial. A black oxide treatment features a wide range of unique characteristics and benefits, many of which are applicable to a seemingly infinite number of industries. These include:
- Corrosion Protection – A recent study has shown that black oxide coating provides corrosion resistance on par with 144 hours of salt spray exposure. This means that a blackened product is not only more durable, it also features a much longer lifespan.
- Dimensional Constancy – If you paint or “plate” a metallic surface, you are essentially increasing its size. Black oxide treatments, on the other hand, add no more than 10 millionths of an inch to the measurements of the part in question. This means that metal blackening is very effective at protecting critical-size parts in many different applications.
- Aesthetic Improvements – Any blackened product will feature glare reduction. Whether you’re working with moving machine parts or surgical implements, being able to avoid glare under bright lights is very important. To boot, black oxide also bolsters the metal surface’s adhesion properties. This means that if you apply a coat of paint, it will not chip, or crack.
- Affordable Rates – Recreating the protective properties and aesthetic appeal of blackened metal is next to impossible, especially for people on a budget.
