How corrosion effect on electrical resistance
WebThe effect of sulfur impurities on the corrosion behavior of nanocrystalline and polycrystalline nickel was discussed by Kim et al. 145 One of the critical points to consider is the distribution of sulfur throughout the material. For constant overall sulfur content, the sulfur concentration per unit grain boundary area is much smaller in nanocrystalline … WebTo measure the electrical resistivity of the concrete a current is applied to the two outer probes and the potential difference is measured between the two inner probes. Empirical tests have arrived at the following threshold values which can be used to determine the likelihood of corrosion. • When ρ ≥ 120 Ω-m.
