VCFERROUS - HOT BLACKENING SALT
"VCFerrous" refers to a type of hot blackening salt used in metal finishing processes, particularly for ferrous (iron-based) metals. This salt is used to create a black oxide coating on the surface of ferrous metals through a process called hot blackening or black oxide finishing.
Hot blackening involves immersing the metal parts into a heated solution of blackening salts, which typically contain a mixture of chemicals such as sodium hydroxide (lye), nitrates, and nitrites. The exact composition of the blackening salts can vary based on the specific manufacturer and application requirements.
The black oxide coating formed on the metal surface provides several benefits, including corrosion resistance, improved aesthetics, and increased wear resistance. It also helps to reduce light reflection, making it suitable for certain optical applications.
