Copper is very corrosion resistant - it does produce a very attractive green patina e.g on the roofs of mosques. To eliminate it entirely - constantly paint it - or use Impressed Current Cathodic Protection. I would not bother

How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
Why did they stop making pennies out of copper?
The US made pennies of copper (95%) in 1941 and 1942, and partially from old shell casings in 1944 and 1945 (so the copper content may have been slightly lower in those years). Only in 1943 were pennies made of steel (with a zinc coating) in an effort to save copper for use in the war effort. Probably because they needed copper for the world war 2 effort. ww2 the need for wiring in the military Short answer: The US was using all the coper for munitions used for WWII. copper was required for the war effort i.e. to make electrical cables
Describe how crystals of copper sulphate are prepared?
You need to start with a copper compound and react it with an acid to get the salt you want. If you use hydrochloric acid you will get a chloride; if you use nitric acid you will get a nitrate. You asked for copper sulphate so can you decide for yourself which acid you need? You will need to put this in a conical flask and heat it - if you're heating acids you must wear protective goggles - and add some copper oxide. This is black. It will react and form a blue solution. You need to be sure you have used up all your acid so you must use enough copper oxide to have some left over. Stop heating and filter it to get rid of the rest of the copper oxide. You want to get rid of the water now - if you want to be quick you can evaporate it by placing it in an evaporating basin on top of a beaker of boiling water. If you have time you can just leave it to evaporate slowly at room temperature. If you do it this way you will get nicer, bigger crystals. Why do you think this is? Look carefully at your crystals to see what shape they are.
How can utilities be made safer to avoid damage during and after earthquakes?
Often much of the damage during earthquakes comes from fires and flooding caused by damaged utilities. Gas pipes or water mains can be broken during the earthquakes. Flexible joints in the lines can protect them from breakage and automatic shut-off valves can be used to stop gas and water flow.

What areas of an aircraft are prone to corrosion?
All parts of an aeroplane are subject to corrosion all the time. You can slow down the rates of corrosion by keeping air and moisture and contaminants away from the surface of the metals by applying paints or sealants. One of the worst places for corrosion is around the toilets and galleys. The water in these area's contain a lot of contaminants and if the paint coatings are not perfect, the corrosion begins, and aluminum will disintegrate very quickly. There are many types of corrosion. Corrosion can start from the inside of the metal, called inter granular corrosion. External paint wont stop this. All corrosion is bad and if not removed and reprotected will cause structures to fail.
What agents will stop corrosion on iron?
Uranium
What is the difference between electrical PVC and plumbing PVC?
electrical PVC is not bar pressure tested and is therefore quite thin and does not contain certain chemicles in the pipe to stop water corrosion where as plumbing PVC pipes are tested and generally thicker and must be in order to prevent burst pipes and pressure spikes
What is the function of the organ's stop?
The organ's stop controls the flow of the air into the pipes.
How does paint work to stop corrosion of metal?
The paint prevents the metal from coming in direct contact with air and moisture, which are what cause corrosion.
What is the effects of corrosion on the computer system?
Corrosion can cause the main hardware parts to malfunction or simply stop operating. Corrosion on the power supply unit can cause short circuits and fires.
Why hot in bath ok but hot in kitchen sink dribbling?
Chances are that you have either carbon steel or galvanize steel pipes and that the inside diameter (ID) has deposits of corrosion and or minerals that have reduced the the opening of the pipe to very small diameter. In addition if some of the corrosion products have spalled off, they are plugging the line. Check your pipe comming out of the wall to see if it is copper, if not, shut water off to house and drain down the house by opening a hose bib, then remove the angle stop under the sink and see if the line is plugged, it will be obvious. Good luck.
When did they stop using corrugated metal pipes?
They did'nt
Where is copper wiring in a yacht?

Will keeping steel wool afte use in oil stop its corrosion?
yes it will.
Why do electronics stop working when they get wet?
Either by corrosion or parts short out in the water.
How can you stop copper mining?
Find a substitute for copper and pay everyone in the copper industry for income lost by eliminating copper mining.
