What Causes Metals to Oxidize or Rust?

What Causes Metals to Oxidize or Rust?

All metals,with the exception of the precious metals,will oxidize when exposed to oxygen and an electrolyte (i.e.atmospheric moisture).It is a chemical reaction of the metal surface with the oxygen present in the air that causes some of the metal to corrode (or oxidize) and form the respective metal oxide on the surface.sp.infoOxidation in Metals Mechanism Kinetics Corrosion As in most cases,the oxide formed remains on the surface of metal,the rate of oxidation can be expressed as weight gain per unit area,or how the thickness of the oxide film increases with time.Oxidation usually develops with time ‘t’ according to one of the curves illustrated in Fig.14.8 at a constant temperature,or more curves in

Oct 22,2007·1) The iron can have additives to prevent rusting.Stainless steel has added nickel and chromium which bind to the iron atoms and keep them from oxidizing.I haven't seen stainless steel rust even over long periods of time.2) The iron can be painted or coated with oil,preventing oxygen and water from coming into contact.sp.infoOxidation Behavior of Copper at a Temperature below 300Figure 1(a) shows the surface morphology of the Cu plate after oxidation at 200 °C in air for 10 minutes; fine oxide particles are observed on the surface.This demonstrates that the oxidation of copper takes place at a temperature as low as 200 °C for a short duration.The size of the oxide particles is in the range 50 to 100 nm.
