- Hot blackening, also known as hot black oxide coating, is a chemical conversion process that imparts a durable black finish to ferrous metals like steel and iron. This method enhances corrosion resistance, reduces light reflection, and improves the aesthetic appeal of metal components.
* Process Steps
1. Cleaning: Thoroughly remove oils, grease, and contaminants from the metal surface.
2. Rinsing: Rinse the parts to eliminate any residual cleaning agents.
3. Black Oxide Bath: Immerse the parts in the heated alkaline solution to develop the black oxide layer.
