From limited knowledge I had after an interaction with Prof Sabih akhtar DCE, AMU, assuming steady and uniform conditions, corrosion rate is initially non linear depending on permeation of corrosion causing substances through the cover(strictly depending on concrete homogeneity and isomerism), but once the cover is saturated with corrosion causing compounds, the embedded steel corrosion rate slowly acquires a steady linear relationship with exposure time... Hope it helps...
Dear Daniyal!
corrosion rate depends on different factors and one of the most important is time of exposure. I recommended (handbook of corrosion engineering).

depends the many factors that include time of exposition CL anion, PH, temperature,
Hi
The corrosion rate of a steel embedded in concrete would increase in a drastic manner as a function of exposure time to aggressive solution, i.e., seawater, in a continuous flow condition of the seawater, i.e., erosion corrosion of the composite of the steel embedded in concrete.
