Before it shines, it is built up.
Decorative chrome plating is a metallic coating formed on a part by electrodeposition. At Dro Pur, we use a triplex nickel chrome plating system, built through a sequence of metal deposits applied from the inside out to transform the surface of the part.
-
By electrodeposition
In each bath, the electric current causes the metal dissolved in the solution to deposit on the part as a continuous layer.
-
Multiple layers
The nickel levels the surface and gives it its brightness; the very thin chrome film follows this finish and adds its characteristic tone.
-
Decorative chrome plating
Different from hard chrome, which is used to resist wear on mechanical parts.
Finish and protection, layer by layer.
The coating is formed by four successive deposits on the base metal. Each has a different role within the system.
-
01
Semi-bright nickel
The first layer in the system, more noble than bright nickel. It forms the base of the multilayer coating.
-
02
Bright nickel
Provides brightness and leveling. Its electrochemical potential is lower than that of the semi-bright layer.
-
03
DurNíquel
The third nickel layer, containing inert particles, is associated with the formation of micropores in the final coating.
-
04
Chrome
An outer deposit applied electrolytically after activation. It gives the surface its chrome finish.
What we bring to the part.
The triplex nickel system provides corrosion protection and a bright finish, preserves the part's appearance over time and withstands handling and cleaning.
Performance depends on surface preparation, coating thicknesses and service conditions.
