VCFERROUS HT Hot Blackening Chemical - Hot blackening is a chemical process used to create a durable black oxide layer on the surface of ferrous metals such as steel, stainless steel, and cast iron. This process provides corrosion resistance, enhances appearance, and reduces light reflection. Here\'s an overview: * Steps in the Hot Blackening Process 1. Cleaning: - Parts are thoroughly cleaned with alkaline solutions to remove contaminants. 2. Water Rinse: - Cleaned parts are rinsed to prevent contamination of subsequent tanks. 3. Hot Black Oxide Bath: - The metal is immersed in a hot solution (typically around 135–150 °C) containing oxidizing salts, forming the black oxide layer. 4. Water Rinse: - Another rinse step removes residues from the blackening solution. 5. Sealing: - Parts are dipped in oil, wax, or another protective sealant to enhance corrosion resistance and achieve a uniform finish. #VCFERROUS HT Hot Blackening Chemical Manufacturer.
