What is corrosion resistance?
Corrosion Resistance. Definition – What does Corrosion Resistance mean? Corrosion resistance refers to the resistance a material offers against a reaction with adverse elements that can corrode the material. Various materials have this property intrinsically, depending upon their corrosion resistance rate.
Is corrosion a physical or chemical change?
Corrosion is a chemical change. Combinations of elements or compounds in a system that can combine and go into a more stable stable state (lower energy state) eventually do so. An example is a steel part rusting as the iron combines with oxygen in the air (salt and water speed this up).
What materials are resistant to corrosion?
Corrosionpedia explains Corrosion Resistance. The materials most resistant to corrosion are those for which corrosion is thermodynamically unfavorable. Some metals have naturally slow reaction kinetics, even though their corrosion is thermodynamically favorable. These include metals such as zinc, magnesium and cadmium.
What is the difference between physical and chemical properties?
A physical property measurement might change the arrangement of matter in a sample but not the structure of its molecules. When a chemical change or reaction occurs, then the characteristics observed are deemed to be chemical properties.
