What is it?
a treatment that allows to deposit chemically a layer of nickel on the
pieces immersed in the bath of nickel plating, without using electrical
current, ie, without exploiting the galvanic effect. The deposit
obtained will have
a very uniform thickness because it is not
subject to the effect "tip"
of the classical electrolytic
processes: on one particular like the radiator on the right, after an
electrolytic process, you have several tens of microns deposit on the
tips, a few microns at the bottom of the gorges and nothing inside the
cavity. The process of chemical nickel plating allows to deposit a
uniform layer of nickel, on the whole surface immersed in the bath and
washed by the liquid, with a difference of a thickness of only + / - 2%
and a tolerance on the thickness required total of + / - 5 %d total of +
/ - 5 %
How is it?
The thickness of the deposit may be very high, reaching
70 -100 microns
proper precautions and with great patience, because the thickness of the
deposit that you get in an hour on average is of the order of 15 microns,
in an electrolytic bath we would take less than 20 minutes to reach the
same thickness, ie approximately one third of the time! There are two
types of toilets: those who deposit a nickel-boron and the now more
prevalent as our Nikelchimico depositing a
with a P content of between 7% and 13%
technological treatment costs are considerably higher with electrolytic
decorative treatments, but it is handy when you require
high mechanical properties and corrosion resistance.
The nikelchimico you can deposit on almost all ferrous alloys, cast
irons, stainless steels, aluminum and its alloys, brass and copper on
many types of plastics, not be deposited on lead, zinc and their alloys
and on nitrided steels or cemented.

polished the piece does not make, as the electrolytic nickel, which
smooths small surface roughness by depositing different thicknesses.
