There are multiple reasons to use black oxide treatment for die castings, and it can provide a variety of benefits to the final product. Black oxide treatment, also known as blackening or blackening treatment, is a chemically converted coating that can be applied to a variety of metal surfaces, including die castings. Some of the reasons why our company produces die castings with black oxide treatment:
1. Enhancement of aesthetic appearance: Black oxide treatment can make the die castings obtain a uniform and beautiful black surface. This is especially useful when you want to enhance the visual appeal of your product, achieve a sleek and modern look, or contrast with other parts or materials in your assembly.
2. Corrosion Resistance: A black oxide coating provides a thin protective layer against corrosion and oxidation. While it is not as effective as more robust anti-corrosion coatings such as electroplating or anodizing, it still provides some protection against environmental elements and moisture.
3. Reduced light reflection: A black oxide coating reduces light reflection from the surface of the die casting, which may be desirable in applications where glare or reflection needs to be considered. This can be useful in applications such as optical devices or equipment used in low light conditions. 4.
4. Lubricity: Black oxide coatings add a lubricating layer to the surface, reducing friction and increasing wear resistance. This is especially beneficial in applications where moving parts need to run smoothly. 5.
5. Improved Adhesion: Black oxide coatings can be used as a primer for subsequent paint or coating processes. It enhances the adhesion of paints, lubricants or other coatings, making it easier to achieve a long-lasting, durable finish.
6. No change in dimensions: Black oxide treatment does not significantly change the dimensions of the die casting, making it a suitable choice where precision and tolerances are critical.
7. Reduce light reflection: The black surface of the black oxide coating can reduce light reflection.
