Corrosion is the gradual chemical or electrochemical attack of a metal or alloy by agents in the surrounding atmosphere. The resulting reaction causes disintegration of the surface and material loss due to either the conversion of the component metal or alloy into a less adherent material such as an oxide or sulfide, or the dissolution of the material into the environment itself. In many cases, wear mechanisms may also be present and exacerbate the subsequent material loss.
Corrosion resistant coatings protect metal components against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals. Anti-corrosion coating allows for added protection of metal surfaces and act as a barrier to inhibit the contact between chemical compounds or corrosive materials.Such coatings also provide a bonus of abrasion resistance, non-stick performance and chemical protection.
Benefits of applying corrosion resistant coating:
- Improves functionality with a longer part life cycle.
- Increases fuel economy when applied to certain automotive parts.
- Lubricates parts which reduces load caused by friction.
- Lowers cost of servicing requirements as parts last longer.
- Resists harsh chemicals and extreme temperatures.
