摘要：
The influence of several naphthol derivatives on the corrosion behavior of titanium in 10 N H2SO4 solution has been studied by measuring the weight loss and analysing the polarization curves, electrode impedance, voltammograms and UV-visible spectra. 1-(2-pyridylazo)-2-naphthol (PAN) is an excellent inhibitor for titanium corrosion in concentrated acid solution at room temperature, 35 degrees C and 55 degrees C, even at a low concentration of 2 mM. Its inhibition efficiency is higher than that of some well-known organic inhibitors for titanium corrosion at high temperature. The stability of PAN as an inhibitor and the influence of the surface state of titanium on the inhibition efficiency of PAN have also been investigated.
