The ability of the metal to resist corrosion in atmosphere with moist.corrosion ocuurs in ferrous materials in which ferrous chemically react with oxygen forming rust or corrosion. Corrosion can be avoided by Heat treatment and surface coating .
Foam resistance is a term that is commonly used in companies that create injection molds and fire resistant equipment. This term means that a product is able to resist damage or corrosion when it is in direct contact with chemicals or solvents.
Electroplating is used for components and equipment in all fields of technology to: 1.protect the material against corrosion 2.improve the surface properties 3.achieve optimum decorative effects
- ability to resist to corrosion and errosion- low toxicity- low cost
Insulators
ability of the material to resist the temperature
