Black oxide is a conversion coating used mainly on iron & steel. It results in a black, smooth surface finish, and improves corrosion resistance and wear resistance.
Black oxide is commonly used as a surface finish in a variety of industrial and commercial applications, including automotive and aerospace components, machinery and tools.
In Ulision, our Black Oxide chemical is environmental friendly & Energy saving chemistry which are able to be coated to a variety of Steel and Iron components.
What were the early uses of black oxide coating?
Preventing corrosion. Black oxide coating helps improve metal components’ resistance to corrosion and rust, extending their lifespans and reducing the need for expensive or time-consuming repairs or replacements.
- Preventing corrosion. Black oxide coating helps improve metal components’ resistance to corrosion and rust, extending their lifespans and reducing the need for expensive or time-consuming repairs or replacements.
- Reduced wear. Black oxide enhances the hardness and durability of metal surfaces, reducing wear and tear and improving the performance of metal components in hard-working or industrial environments.
- Aesthetics. With a smooth, matte finish, black oxide improves the appearance of metal components, making them easier to incorporate into a variety of applications, as their visibility is not an issue.
What is black oxide predominantly used for now?
Black oxide is still used to achieve the above results, and is well-suited for applications that require a durable, low-maintenance, and corrosion-resistant surface finish, such as:
Fasteners, hardware, and tools. Black oxide is a popular finish for fasteners such as screws, nuts, bolts, as well as hand tools and other hardware, as it provides a matte, aesthetically pleasing finish that is corrosion-resistant, durable, and easy to grip.
Automotive and Aerospace components. In the automotive and aerospace industries, black oxide is used as a surface finish for a variety of parts, including engine components, suspension systems, and landing gear.\
Industrial equipment. Black oxide is used to finish a wide range of industrial equipment, such as pumps, valves, and machinery, to provide corrosion- and wear-resistant surfaces.
