It has been found empirically that the stiffness degradation can be accurately modeled by the pivot rule (Park et al. 1987) Rheological models There exist a big number of rheological models in the literature, but most of them have more or less led to results that agreed physically with reality.

In the present paper, inhibition effect of acridine on corrosion of hot dipped Zn and Zn-Al alloy coatings on steels in diluted hydrochloric acid was investigated using weight loss test, electrochemical measurement, and quantum chemistry analysis.
Experimental Commercial available hot dip Zn (GI), 5%Al-Zn (GF) and 55% Al-Zn (GL) coated low carbon sheet steel were used as test samples.
It could be found that corrosion potential (Ecorr) values changed within 20mV for all the three coatings, therefore, acridine behaved with mixed-type inhibition for hot dipped Zn and Zn-Al alloy coatings in HCl solution.
Conclusion Acridine was an effective environment-friendly inhibitor for hot dipped Zn and Zn-Al alloy coatings in hydrochloric acid.
