Metal blackening is a process in which the surface layer of a metal material is transformed into black. This is achieved through a chemical reaction between the metal and a solution containing metal ions. This process is often used to protect metal surfaces from corrosion and enhance their aesthetic appearance. During blackening, the metal material is first cleaned and then immersed in a solution containing metal ions, which is subsequently heated to a specific temperature.
We blacken parts according to the maximum size of the tank - 400×300×180 mm, and the maximum weight of parts - 20 kg.
