Why is ferrous alloy has more corrosion resistant then iron?
An alloy is a mixture of metals and a ferrous alloy is an alloy who's main constituent is iron. Iron in itself is extremely susceptible to corrosion, however, with the addition of other metals to create a ferrous alloy, such as the addition of slag (Such as in wrought iron), Nickel (Alnico, Invar, etc), Maganese (Bismanthol), Chromium (Kanthal), Titanium (Ferrotitanium) and so on give the alloy it's corrosion resistance. So, in short, almost, if not all ferrous alloys contain a constituent that is corrosion resistant, hence why ferrous alloys are more resistant to corrosion that straight iron.
Why does chromium in stainless steels make them more corrosion resistant in many environments than plain carbon steels?
Chromium forms a tough, adherent ,extremely corrosion resistant, oxide - chromium oxide on the surface. It is the chromium oxide that is extremely corrosion resistant. It also adheres extremely well. Iron oxide - rust does not adhere well - all to do with the Pilling-Bedworth ratio. It is also why Aluminum is very corrosion resistant. It forms a thin adherent layer of aluminum oxide on the surface.
What are the properties of resistant and non resistant materials?
Resistant materials have the ability to withstand wear and tear, corrosion, and high temperatures, making them durable for various applications. Non-resistant materials are more prone to damage and degradation when exposed to harsh conditions, making them less suitable for demanding environments. The choice between resistant and non-resistant materials depends on the specific requirements of the application.
What is platinum in its pure form?
It is a whitish, highly-malleable metal but with hardness equal to iron and highly resistant to corrosion. When impure, as with osmium or rhodium, it is more brittle.
Which is stronger Aluminium corrugated sheets or galvanised iron corrugated sheets?
Aluminium corrugated sheets are generally stronger than galvanised iron corrugated sheets because of the inherent strength of aluminium as a metal compared to iron. Aluminium is also more resistant to corrosion, making it a more durable option for outdoor applications.
What material is better - stainless steel or carbon steel?
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
What are the differences between towel hooks and towel bars, and which one is more suitable for organizing towels in a bathroom?
Towel hooks are individual hooks that hold towels by hanging them over a single point, while towel bars are long rods that towels are draped over. Towel bars are better for organizing towels in a bathroom as they allow for towels to be spread out and dry more efficiently.
What is the Metal is corrosion resistant?
Well the way you phrased your question is that one is more than another but actually there are multiple such as Nickel,Aluminum,and Gold. Whitch are all equally corrosion resistant.
What happens to galvanised iron which is exposed to air and water?
It is more resistant to corrosion.
How do you protect construction steel bars from corrosion?
the concrete cover protects the steel bars from corrosion and environments or members more prone to corrosion or chemical attack such as in footings the cover thickness is increased in members where the concrete will come to direct contact with the soil a blinding layer of about 10cm is used to separate the reinforced concrete from the soil. also coating steel bars in corrosion resisting chemicals is used for more protection
Why aluminium resistant to corrosion?
Aluminum is resistant to corrosion due to a thin oxide layer that forms on its surface when exposed to air. This oxide layer acts as a protective barrier, preventing further oxidation and corrosion of the metal. Additionally, aluminum's reactivity with oxygen is relatively low compared to other metals, making it more resistant to corrosion.
Why is aluminium used in airoplanes?
because it is ductile, malleable and more importantly light weight and resistant to corrosion
Why is ferrous alloy has more corrosion resistant then iron?

What are the differences between galvanized and stainless steel in terms of their durability and resistance to corrosion?
Galvanized steel is coated with a layer of zinc to protect against corrosion, making it durable and resistant to rust. Stainless steel, on the other hand, is inherently corrosion-resistant due to its composition of chromium and nickel. Stainless steel is generally more durable and has a higher resistance to corrosion compared to galvanized steel.
Why does chromium in stainless steels make them more corrosion resistant in many environments than plain carbon steels?
Chromium forms a tough, adherent ,extremely corrosion resistant, oxide - chromium oxide on the surface. It is the chromium oxide that is extremely corrosion resistant. It also adheres extremely well.

How do manufacturers of tin cans prevent corrosion from occurring?
Manufacturers prevent corrosion on tin cans by applying a protective coating on the inner surface of the can, usually made of a polymer or epoxy resin. This coating acts as a barrier between the metal and the contents of the can, preventing corrosion. Additionally, some manufacturers may also use tin-plated steel or stainless steel to make the cans, which are more resistant to corrosion.
What is the difference between steel and staniless steel?
Stainless steel contains a minimal of 13% chromium and is much more corrosion resistant.
