The weight loss is converted to a corrosion rate (cr) or a metal loss (ml), as follows surface finishing methods vary across a broad range for specific applications.
47+ Corrosion Rate Weight Loss Method
Gif. It involves recording the difference in weigh over specific time intervals. To can obtain density of the test sample from its mass ans volume.
Table 2 From Corrosion Inhibition By Trisodium Citrate Tsc Zn2 System Semantic Scholar from d3i71xaburhd42.cloudfront.net
Pitting is a form of localized corrosion: Briefly, carbon steel coupons (20#) were immersed in 250 ml glass bottles filled with oil well production water. Some approaches for estimating this information are given.
This is perhaps the simplest corrosion monitoring since it only deals with time and weight.
Corrosion rate is calculated assuming uniform corrosion over the entire surface of the coupon. The corrosion rate (at the oil well temperature) was determined according to the weight loss method with the wells temperature in a week. From the following table, the density is found to be 7.85 g/cm3. This is perhaps the simplest corrosion monitoring since it only deals with time and weight.
