Definition - What does Micron mean?
A micron is a unit of measurement. It is used to replace other terms of measurement such as "one millionth of a meter" and "micrometer."
One micron can be expressed as 1/25 of a thousandth of an inch or one thousandth of a millimeter. This measurement has many applications, but in terms of corrosion, microns as measurement can be applied in coatings and other industrial applications. The proper thickness of paint or coat must be achieved to prevent corrosion and any form of damage from occurring.
Corrosionpedia explains Micron
Coatings are used to provide protection against corrosion. Significant improvement in the corrosion resistance of such coatings or films has been proven though proper application. In order for a coating to serve its purpose, proper thickness must be maintained during application.
In addition to coating applications, microns can be used in a variety of machining and engineering purposes. Industrial workers such as machinists, boilermakers and millwrights make measurements in microns and other fractional measurements. The use of these measurements has necessitated the introduction of screw micrometers, vernier calipers and other tools to measure sizes in fine detail.
The contribution of microns as a measurement can also be seen in the fields of microchips and fiber optics. Microns are used to measure the core of optical fibers, with a common diameter of about 60 microns, while the width of microchips measure about 0.13 to 0.18 microns.
