Question

Difference between corrosion of metal and ceramics

Answer 1

Chemical deterioration is most common in metals, and also observed to some extent in ceramics. It is known as corrosion. ➢ Physiochemical deterioration of polymers is known as.

Answer 2

Answer:

The difference between corrosion of metal and ceramics is as follows

• Corrosion is a natural process that converts the metal to its more stable oxide. The surface of the metal comes in contact with the gas or liquid.
• It is the deterioration of materials by the action of the chemical reaction.
• Metals are lustrous, opaque materials and are used widely due to the ease of manufacturing.
• Ceramics are inorganic, non-metallic materials.
• Corrosion in general oxidation of metals like iron. But ceramics can also react with the environment surrounding them. Like tungsten carbide is highly resistant to corrosion. It's destroyed when comes in contact with sulfuric acid.
• Ceramics are preferred over metal because of their strong ionic or covalent bonding. And metals have less stable metallic bonding.
• Ceramics have high hardness, strength, and low thermal and electrical conductivity. And metals have high thermal and electrical conductivity.
