A friend of mine got me interested in checking out the Metal Gear video game series. I know that the PlayStation games start out with the first Metal Gear Solid game, and before that, there were two Metal Gear games for the NES. Unfortunately, I don't have an NES system, but I am really interested in checking the games out. So, my question is, is it really necessary to play the NES Metal Gear games in order to start on Metal Gear Solid? Does playing Metal Gear give you any understanding of the series needed for playing the first Metal Gear Solid game?
3 Examples of metals which are used to coat other metals would be Gold, Chromium, and Zinc. Gold is used to coat other metals for a couple of reasons, 1) Gold is a ‘pretty’ metal which people will pay money to have things made of. But Gold is also an expensive metal (several hundred dollars per ounce), so one can get the same visual effect of having a gold ___ if it is just gold-plated and not solid gold, thus making it cheaper. 2) Gold is a chemically inert metal; it will not react with many things, and also has a very high electrical conductivity, so coating some other metal with gold will improve its chemical resistance to corrosion and lower its electrical resistance. Chromium metal is used to coat other metals for similar reasons, --Chromium is less reactive than many other metals so one can “Chrome-plate” a more reactive metal with Chromium and help protect the metal from corrosion. For example, many car’s have ‘chrome-plated’ bumpers. is --Also, Chromium is a visually appealing metal so having a nice shinny Chrome-plate bumper is considered more desirable than a rusty old Iron bumper. Zinc metal is used for a much different reason, --Zinc is more chemically react than most other metals and is not a particular pretty metal either. Zinc is often used as a sacrificial metal to help protect other metals. For example, many things like nails, screws, washers, …., are Zinc-plated to help protect those [Iron] parts from rusting. The Zinc will oxidize before the Iron, thus protecting the Iron at the expense of the Zinc.
Like for example sometimes fake gold jewelry is really just nickel with gold plating. its done just to give something more value i guess, to rip people off. so theres gold and silver, maybe titanium.
copper nickle silver gold palladium we use all of these in the jewelry business. Some metals are more easily attracted to others. for instance to plate with gold over plastic you would start with copper dusting then nickle then the gold would plate on to the item.
The primary reason for coating one metal with another is corrosion resistance. You might also do it for decoration, or to provide a wear or bearing surface, or to make a good electrical contact. Many things (tools, automotive parts, etc) are plated with copper and then nickel and then often chromium, to give them both corrosion resistance and a nice shiny chrome finish. The chromium gives an attractive bluish tint to the part, but it's the nickel that is the heavy layer giving you the mirror-like surface and most of the protection. Outdoor steel is often coated with zinc, called galvanization, either by electroplating or by dipping the steel into molten zinc. The zinc corrodes sacrificially to the steel it is protecting. Many things are gold plated for decorative purposes, to prevent oxidation, to improve electrical conductivity, or all of the above. You often see gold plated electrical connectors on high-end audio gear.
depends, gold and silver to protect and for looks, zinc for galvanizing to stop corrosion
