Calculating Corrosion Rate

The corrosion rate is often expresed in mils per yeAR (mpy) or millimeters per yeAR (mm / y). Te basic formula involves mesuring the loss of materiala over timee:

11; Syarion1; FLT: 0 AF3; Corrosion Rate = (K × W) / (A × T XD) Syon1; FLT: 1 23; Aver3;

Dimana:

  • FL1; FLT: 0 = 0 = 133; K = 1f 1; FLT: 1: 1 13; = a constant (e.3 x 10; FLT: 2: 6 GS3; FLT: 3: 3: 3F; for mpy)
  • S01; WAL1; FLT: 0 AF3; W 1; FLT: 1 ASA3; = weifft loss ilar
  • Pertama; FLT: 0 = 0 = 33; A £1; FLT: 1 = surface ea in square centimeters
  • 1f 1f; 1f; FLT: 0 133; T 1f; FLT: 1 1f 3; = time in hours
  • Pertama; FLT: 0 = 0 = 3I; D = 1f; FLT: 1: 1: 1 Aver3; = densit of the materiala g / cm 1; FLT: 2 MIL; 3 MISKIN; 3 MISKIN 13;
