Corrosion Rate Meter & Sensor

Corrosion is the most costly type of loss. Corrosion is caused by chemical and electrochemical reactions of metallic materials with environmental media (operating media, water, steam, air, gas, gas, and other analogues). Corrosion is defined as: corrosion is the chemical and electrochemical reaction between metal and its environment resulting in the destructive invasion of metal phenomenon.

What is corrosion rate?

The corrosion rate is the rate at which any metal degrades in a given environment. It can also be defined as the amount of corrosion loss per year in terms of thickness. The rate or speed of deterioration depends on the environmental conditions as well as the type and condition of the metal being referenced.

When calculating the corrosion rate for any given metal, several pieces of data must be collected. The data required include:

  • Weight loss (the reduction in weight of the metal during the reference period).
  • Density of the metal.
  • The total surface area initially present.
  • The length of time spent.

What is corrosion formula?

Use the following formula to calculate corrosion rate from metal loss data:

Rcorr (mm/yr) = 87.6 x (W/DAT)

W = weight loss in milligrams
D = metal density in g /cm3
A = area of the sample in cm2
T = exposure time of the metal sample in hours
