Parts Breakdown
TEA
Coating
Eco
Friendly intermetallic electro deposited alloy
Stable:
The absence of porosity in this alloy guarantees resistance to
corrosion and long-term permanence of its shine
Deposit
Specifications:
TEA
is used to produce polished deposits, with solid guarantees for
resistance to wear and corrosion.
The
deposit color is consistent regardless of changes of product
concentrations in solution; even if deposited on mechanically
satin-finished surfaces, or with satin-finished nickel base.
TEA
alloy produces the desired decorative effect.
Morphological
Analysis:
Under
a light microscope the coating has a glassy and shiny appearance
In
polarized light the underlying metallic brass substrate seems to be
visible in certain points.
The
morphology of TEA was analyzed using a scanning electron microscope.
With
EDX analysis the composition of the deposit is as follows (the % are
in weight and normalized only for the identified elements, the
accuracy is +1.5%)
Nickel:
32%
Tin:
68%
The
composition is compatible with a TEA structure composed of SN and NI
atoms in a 1:1 ratio.
TEA
Corrosion Tests
Samples
underwent corrosion testing by immersing them in 2 different buffer
solutions:
-
PH
2.3
-
PH
10
The
PH values were selected based on the extreme values reached by foods
(for ex: acetic acid, PH 2.3/2.4 - albumen, PH 9/10)
Under
light microscope the TEA deposit did not show any particular signs of
yielding to the attack of the used solutions. Aesthetically the
deposit remained shiny and no significant differences were found
between before and after immersion.
TEA
replaced the traditional nickel-chrome electrolyte deposit.
