What is sacrificial coating?
When a more reactive metal sacrifices itself for a less reactive metal to prevent the lesser reactive metal from rusting. :-)
How does sacrificial protection work?
Sacrificial protection is basically attaching a piece of metal that is more reactive that iron to the object made of iron. This more reactive metal, commonly magnesium or zinc, will corrode in the place of iron. That is, the more reactive metal will feed the iron with electrons each time the iron is oxidised to form iron ions, thus reverting it to iron once again instead of letting it become iron hydroxide (rust). Thus, the more reactive metal is sacrificed for the iron.
How do you stop metal rusting in salt water?
To prevent metal from rusting in saltwater, you can apply a protective coating such as paint, oil, or a corrosion-resistant metal coating like zinc or stainless steel. Regular cleaning and drying are important to remove salt residue and prevent corrosion. Additionally, using sacrificial anodes or cathodic protection can provide an extra layer of protection by redirecting corrosion to sacrificial metals.
How does sacrificial anode protect a submerged pipeline?
Just have a crack at Sacrificial anode in wikipedia.org.
What can you use for sacrificial protection of iron nails?
A more reactive metal which is electrically connected to the nail. Typically, zinc is used to coat the iron nail (hot dip galvanizing)
Can metal used to provide sacrificial corrosion?
Yes, they metal used is called an "sacrificial anode".
What is a sacrificial anode?
A sacrificial anode is a piece of corrodible metal which is preferentially consumed by electrolytic action.
What metal is used for rust prevention?
Zinc is often used as a sacrificial metal on iron.
Why is sacrificial metal used on the construction industry?
the reason that that they use thattype of metal is that its cheaper
What metal is commonly used as sacrificial?
Magnesium and zinc are often used

What is a sacrifical metal?
I've never heard that exact phrase used, but I'm guessing you're talking about a sacrificial anode. This is a piece of more active metal that's electrically connected to a piece of metal you want to protect; the sacrificial anode corrodes instead of the less active metal.
How do sacrificial metals protect ship's hulls?
Sacrificial metals work in accordance with the "galvanic series" - the potential for current flow from one metal to another. If you put two metals in an electrolyte, of which seawater is a good one, the less noble or "more anodic" metal will corrode and save the more noble or "more cathodic" metal from corroding. Zinc, being both highly anodic and very cheap to purchase, is the standard sacrificial anode on ships.
Why is gold not used for sacrificial protection?
Sacrificial protection is only effective if the metal used for sacrificial protection is more reactive than Iron in the reactivity series. Since gold is one of the least reactive metals in the reactivity series, it would not get oxidized in the place of Iron. A more reactive metal than Iron, e.g. Zinc, is used as the Zinc metal would oxidize in the place of iron, thus preventing Iron from rusting.
When was Sacrificial Bonfire created?
Sacrificial Bonfire was created in 1986.
