The volume resistivity of all fibre rubber composites increases with the increase in temperature, and the rate of increase in resistivity against temperature depends on the loading of carbon fibre and the nature of the base polymer.
In general, at 500 °C, by increasing flow rate of oxygen, the resistivity of layers decreases systematically.
As time increases, gas diffusion slows down in the film, leading to a corresponding slowdown of the resistance decrease rate, resistivity finally reaching stability.
In particular, for GZO films prepared with a Ga2O3 content of 4 wt.% at an O2 gas flow rate of 2.5 sccm, the lowest resistivity of 2.23 × 10− 4 Ω cm was obtained; the carrier concentration and Hall mobility were 1.17 × 1021 cm− 3 and 23.9 cm2/Vs, respectively.
During the wet cycle, pore volumes get saturated, and the rate of corrosion increases as the resistivity of the specimen decreases.
Several conventional data, e.g., aquifer electrical resistivity, pumping rate of production wells, and aquifer thickness are used in the introduced approach.
A higher value of resistivity index represents greater resistance of vasculature, indicating deleterious significance.
The corrosion characteristics of fly ash and slag cement concretes were studied through measurement of resistivity, pH, carbonation, and corrosion rate.
Meanwhile, the evaluation criterion for corrosion risk of steel reinforcement based on concrete resistivity was proposed according to the relationship between concrete resistivity and corrosion rate of steel reinforcement.
