YELLOW CHROMATISING CHEMICAL
Yellow chromating involves immersing the metal substrate into a solution containing chromic acid, typically with additional additives such as accelerators and inhibitors. During the process, a thin layer of chromate compounds forms on the metal surface through a chemical reaction. This chromate layer provides a protective barrier against corrosion by acting as a sacrificial coating.
The color of the chromate conversion coating can vary depending on the specific formulation and process parameters. Yellow chromate coatings are popular due to their distinctive yellowish hue, but other colors such as clear, iridescent, or black are also possible.
