Molecular formula : MW : CAS :
nature : measurement of metal corrosion rate of a classical method. Practice is the unknown samples by metal surface treatment (of wear, decontamination, etc.), the precise measurement of its surface area (So) and weighing (Wo). Then certain temperature, pressure and mixing conditions, to put corrosion medium, by a certain time (t) after removal, cleaning, removing corrosion products attachment after re-weighing. According to corrosion around the calculated weight of poor corrosion rate ( υ ) : υ = Wo-Wt/So t. Determination of weightlessness average corrosion rate. Its advantage is simple and has the disadvantage of low corrosion rate of occasions, measuring the time required for long.
