If you’ve been using a protective paint or some sort of rust-proofer to safeguard your tools, gadgets, and industrial machinery, it’s important to note that you have a much more efficacious and affordable option at your disposal in today’s day and age.

This brief article will cover all of the ins and outs of contemporary black oxide applications, which are otherwise referred to as metal blacking.

What Is Metal Blacking?

In its simplest sense, metal blacking (or metal blackening) involves applying a unique chemical compound to the surface of a particular substrate in an effort to change its molecular composition. This is far different from applying a protective overcoat or corrosion deterrent because you are essentially altering the host material’s surface and creating a porous base.

To better understand why metal blacking is so effective, let’s take a look at the process on a step-by-step basis:

  1. The contemporary room temperature metal blacking process begins by carefully cleaning and scouring the implements and tools in question.
  2. Then, batch operators will dip the workpieces into a tank containing a proprietary black oxide mixture. This step of the process is usually conducted by way of automated parts carriers or simple dipping baskets.
  3. Upon entering the tank, the black oxide mixture will seep deep into the molecular apertures of the workpiece in question.
  4. After a rapid chemical transformation, the substrate’s surface establishes a steadfast bond with the black oxide base, fundamentally changing the host material’s exterior coat.
  5. To finalise the process, operators apply an industrial sealant to the workpiece. The sealant, which is usually some sort viscous, heavy-duty lubricant, seeps into the tiny microscopic pores of the black oxide coating and establishes an impermeable layer of corrosion protection.

Why Is Metal Blacking So Desirable?

If you partner with a reputable commercial metal blacking company such as Blackfast, for instance, you’ll be able to redefine your entire assortment of industrial tools, implements, and apparatus:

  • Corrosion Protection: The inimitable amalgamation of black oxide and industrial sealant provides unmatched protection against erosion, rust, molecular deterioration, and decomposition.
  • Dimensional Constancy: When compared to painting or plating, both of which add significant bulk to a given workpiece, it’s important to note that metal blacking adds less than 254 of a micrometre to the breadth of the item.
  • Glare Reduction: Black oxide’s matte finish negates the light-based shimmers and flashes that tend to create headaches for operators all around the world, which makes it the perfect protective solution for moving parts and complex surgical tools.
  • Improved Adhesion: Apart from the fact that black oxide can withstand over 200 hours of salt spray and several hundred hours of excessive humidity, it’s worth mentioning that this protective coating also responds very well to additional layers of paint or coating. As such, subsequent applications will not chip, crack, or blister.
  • Aesthetics: The striking jet-black finish augments both the perceived and intrinsic value of a vast array of workpieces, devices, and tools. Thus, metal blacking is the perfect solution for not only industrial applications but also for showroom items and even sales floor products as well.
