Attack Of The Nib Eater

[More4dan]

There is a problem with plated metals in any corrosive environment. The gold plating will actually drive the stainless base to corrode where it wouldn't without the plating. Dissimilar metals set up a galvanic pair where the more noble metal is protected and the other corrodes. Gold is the most noble metal and the stainless steel base becomes a sacrificial anode. The corrosion will be accelerated at the place where the plating has any defect and at the interface of plated and unplated.

 

Use a polished Stainless Steel nib or solid gold for corrosive inks.

Hi,

 

Many thanks for explaining why gold plated parts are vulnerable, which will help us choose our ink+pen combos with care.

 

Mr. Richard Binder also mentions the vulnerability of gold plated parts. Other than the nib, I reckon a plated section ring [ferrule] is at risk of damage due to inadvertent contact with ink bottles when inking-up and with caps when replacing them does not go smoothly.

Bye,

This "galvanic" corrosion only happens when to 2 metals are wet with the corrosive liquid.
