| For the galvanic protection of steel, like in marine ships,
| electrodes of zinc, or better of magnesium, are suitable.

| through both to make the nickel acetate, then you're good to go.

| Nickel plating is great because it doesn't tarnish and it doesn't
| tend to corrode, so it always looks shiny. It was super popular

| is probably why it's been replaced by silver plating over the
| years.

|
| I had to look up the cause, and it was because it used a high
| Nickel alloy for the tool steel.
|
| I had not associated Nickel as particularly harmful, but...
| it's relatively nasty in regards to human health (particularly
| when inhaled in even small amounts).
|
| So I was curious and scrolled down to page 81 in the linked
| document on this post - they do a fairly thorough walk through
| of the potential harms, and it's worth reading for the folks
| who do this at home.
|
| I've copied the relevant regulatory warnings from the document
| here:
|
| -----
|
| 1Nickel salts (e.g., Ni sulphate, Ni sulphamate) carry the
| following human health hazard classifications under GHS:
| (Global Harmonized System): Acute Tox. 4 (H302: Harmful if
| swallowed and H332: Harmful if inhaled), Skin Irrit. 2 (H315:
| Causes skin irritation), Resp. Sens. 1 (H334: May cause allergy
| or asthma symptoms or breathing difficulties if inhaled), Skin
| Sens. 1 (H317: May cause an allergic skin reaction), Repr. 1B
| (H360: May damage fertility or the unborn child, developmental
| effects), Muta. 2 (H341: Suspected of causing genetic defects),
| Carc. 1A (H350: May cause cancer by inhalation route only), and
| STOT Rep. Exp. 1 (H372: Causes damage to respiratory tract
| through prolonged or repeated inhalation exposure). Nickel
| metal carries the following human health hazard classifications
| under GHS: Skin Sens. 1 (H317: May cause an allergic skin
| reaction), Carc. 2 (H350: May cause cancer by inhalation route
| only), and STOT Rep. Exp. 1 (H372: Causes damage to respiratory
| tract through prolonged or repeated inhalation exposure).

| Most of those dangers are true for most kinds of metal
| powders or soluble metal salts.
|
| What is specific to nickel is that much more people,
| especially women, are allergic to it, in comparison with
| other common metals. Therefore surfaces covered with nickel
| or nickel alloys with high nickel content are not recommended
| for contact with skin.

| Is it true that nickel plating is less expensive than chrome

| bluGill wrote:
| The trade offs are more complex than that. Depending on your

| more toxic from what I can tell. I used to work at a factory
| that did chrome platting (technically the next building over -
| I never went into that building but it was the same company),
| and so I had to get special safety training before I was
| allowed to work. Mostly my training amounted to we have our own
| sewer system for just the chrome plating work, it can handle
| chrome salts but regular sewage will clog it and cause a toxic
| release - use the regular city sewer for everything else.

|
| It's a good thing that we replaced most of the people-facing
| platings with plastics, because those are some nasty metals.
| The one metal that we still use everywhere is zinc, that isn't
| a big issue.
|
| But nickel in particular allows for a lot of possibilities on
| the plating color, including some very-high absorption blacks.
| (And I think all the high-absorption for solar radiation, low
| absorption for thermal radiation coatings are nickel based.)
