Design considerations for black oxide
When considering black oxide as a design option, it's important to keep the following factors in mind:
- Material Compatibility: Black oxide is typically applied to ferrous metals such as steel, stainless steel, and cast iron. Ensure that the material you choose is compatible with the black oxide process to achieve the desired results.
- Surface Preparation: Proper surface preparation is crucial for a successful black oxide coating. The surface should be clean, free from oils, grease, rust, and scale. Consider the necessary pre-treatment steps, such as degreasing and surface conditioning, to ensure optimal adhesion and uniform coating.
- Desired Finish and Appearance: Black oxide coatings can range from matte to glossy finishes. Consider the desired appearance and communicate your preferences to the service provider. Additionally, black oxide can be combined with other post-treatments like oil or wax coatings to further enhance the appearance and provide additional protection.
- Functional Requirements: Evaluate the functional requirements of your parts. Black oxide coatings offer enhanced corrosion resistance and friction reduction properties. Determine if these attributes align with your specific application needs and consider any additional functional requirements, such as lubricity or wear resistance.
- Dimensional Considerations: Black oxide coatings add a thin layer to the surface of the part. Take into account the coating thickness and ensure that it does not affect the critical dimensions or tolerances of the component. Discuss the coating thickness requirements with the service provider to ensure dimensional integrity.
- Masking and Plugging: If there are specific areas of the part that should remain uncoated, consider the need for masking or plugging those areas before the black oxide process. This can help maintain functional surfaces or prevent unwanted coating buildup.
- Post-Treatment and Handling: Black oxide coatings require proper handling and care to maintain their appearance and performance. Consider the need for additional post-treatment steps, such as applying protective coatings or implementing suitable packaging and storage solutions to prevent scratching or damage during transportation and storage.
- Regulatory and Environmental Considerations: Ensure compliance with any regulatory requirements related to the use of black oxide coatings, such as environmental regulations or restrictions on certain substances. Choose service providers that follow environmentally friendly practices and use eco-friendly chemicals.
By considering these design considerations, you can optimize the integration of black oxide coatings into your component design, ensuring both functional performance and aesthetic appeal.
The V1 black oxide process
Black oxide is a conversion coating, compatible with steel, stainless steel and copper, that provides a black appearance and mildly improves resistance to corrosion of parts.
Here’s how to apply black oxide:
- First run parts through machining and deburring.
- Clean parts using alkaline solutions.
- Rinse in water.
- Black oxidizing. Immerse the part in the hot (135-145ºC) alkaline bath for a period of 5 to 40 minutes depending on the size of the part
- Rinse in water.
- After-finish treatment. Seal the oxide surface with oil, lacquer or wax. This imparts the desired aesthetic appearance and improves the corrosion resistance of the component.
