Friendly intermetallic electro deposited alloy
The absence of porosity in this alloy guarantees resistance to
corrosion and long-term permanence of its shine
is used to produce polished deposits, with solid guarantees for
resistance to wear and corrosion.
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.
alloy produces the desired decorative effect.
a light microscope the coating has a glassy and shiny appearance
polarized light the underlying metallic brass substrate seems to be
visible in certain points.
morphology of TEA was analyzed using a scanning electron microscope.
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%)
composition is compatible with a TEA structure composed of SN and NI
atoms in a 1:1 ratio.
underwent corrosion testing by immersing them in 2 different buffer
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)
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.
replaced the traditional nickel-chrome electrolyte deposit.
