The rate of reinforcement corrosion, commonly expressed as corrosion current density, , is a quantitative indicator of the damage caused to the steel rebars on the other hand, the gravimetric weight loss measurement is a destructive technique for determining the average rate of corrosion [2].
View Convert Weight Loss To Corrosion Rate
Gif. Register at corrosion source in just 60 seconds! Converting the corrosion rate from one unit to another for comparison and for engineering applications is frequently required for numerous metals and alloys.

Corrosion rate is calculated assuming uniform corrosion over the entire surface of the coupon. The weight loss of a corrosion coupon after exposure to a corrosive environment, expressed as mils (thousandths of an inch) per year penetration. To convert mils into inches, you just have to add or remove 3 digits.
When the measured parameter is converted into a for steel, a corrosion current of 1 ma/m2 approximates a weight loss of 10 g/m2yr which in turn approximates a section loss of 1 μm/yr.
The velocity at which the. Corrosion assessment by immersion weight loss measurement and corrosion rate calculation method is applicable with solutions of ph the coupon is then cleaned of all corrosion product and is reweighed. The weight loss is converted to a corrosion rate (cr) or metal loss (ml), as follows weight loss determination has a number of attractive features that account for its sustained popularity: The following charts provide a simple way to convert data between the most common corrosion units in usage, i.e.
