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:

1. PH 2.3

2. 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.

For Drinking Water

NSF 61 section 8 -PH 5 Hot Commercial (82 degrees C), for drinking water system components, considered to be the highest standard in this field.

NSF 4, UNI 10531 and UNI 11460 for professional coffee machines and other “food zone” equipment.

Test performed on 2” spherical valve, yellow body sphere with TEA deposit

NSF Test: 61-section 8 pH 5 Commercial Hot - 82 degrees C
