Black oxide coating is a finishing process in manufacturing that can be used on a range of metals, such as iron, steel, and stainless steel. The metal parts are thoroughly cleaned before being submerged in a hot alkaline bath, which causes a thin layer of magnetite to form on the surface. At Fowler Industrial Plating, we offer multiple black oxide coating services based on each customer’s individual requirements.
Black Oxide Coating Options
As specialists in black oxide treatments, we can provide different coating options to enhance functional and aesthetic properties in different metals. These options include:
Black Oxide Coating for Ferrous Metals
Fowler Industrial Plating offers black oxide coating for ferrous metals, including alloyed steel and various base metals. The resulting finish cuts down on reflectivity and increases wear resistance, making it ideal for reducing glare and protecting against environmental wear.
Stainless Steel Black Oxide Options
We also offer black oxide treatments specifically for stainless steel, which involve applying a coating at mid-range temperatures to produce a finish that maintains the material’s structural stability. It can also reduce glare and enhance the overall appearance of the metal.
Performance of Black Oxide Coatings
There are several key ways a black oxide finish can optimize part performance, including:
- Corrosion and rust resistance. One of the main advantages of black oxide finishing is its enhanced corrosion resistance, which can be significantly increased using oil, wax, and other post-treatment sealants.
- Lubricity and wear characteristics. When used in combination with certain compatible sealants, the black oxide layer can boost wear resistance with less friction. These properties are important for ensuring smooth, consistent movement in treated parts.
- Dimensional stability after coating. Additionally, black oxide finishing minimally impacts part dimensions to maintain a part’s original required specifications. This is due to the fact that these coatings add no more than approximately 0.000020 inches to component surfaces.
Applications
Black oxide finish can be used for enhancing parts in various industries and applications, such as:
- Automotive, Firearms, and Tools: Firearms and automotive parts frequently utilize black oxide coatings for barrels and bolts, along with other components and various tools to minimize glare while improving durability.
- Aerospace, Medical, and Defense: The aerospace and medical industries often implement black oxide-coated parts when dimensional stability and minimal reflectivity are required. For example, aircraft components, surgical instruments, and other parts may use black oxide finishes to optimize precision.
- Fixtures, Gears, and Fasteners: Fasteners, fixtures, and gears also depend on black oxide to minimize friction and increase wear resistance. As a result, this coating is a popular option for applications requiring moving parts with consistently efficient operation.
Selecting the Right Black Oxide Treatment
The right black oxide treatment depends on factors such as the base metal, desired appearance, dimensional requirements, operating environment, and intended application. Ferrous metals and stainless steel require different processing approaches, while the choice of post-treatment sealant can affect corrosion protection, lubricity, and wear performance.
Fowler Industrial Plating evaluates these requirements before processing to help determine the appropriate solution for each application. Our black oxide coating services are tailored to the material, part geometry, production volume, and performance expectations, helping customers achieve the right balance of appearance, protection, and functional performance. This approach also helps ensure the selected black oxide finish is suitable for the part’s intended use.
