- Abstract
- Heritage lead is subject to attack from organic acids emitted from wood and other sources in its environment. Coating the lead is a possible solution if the source cannot be eliminated. We present a study of the growth and corrosion resistance of a lead carboxylate coating, (CH3(CH2)8COO)2Pb, deposited using an environmentally friendly process. Using a combination of synchrotron X-ray diffraction and electrochemical impedance spectroscopy we demonstrate the monitoring of the growth of the coating in real-time in an environmental cell configured for electrochemistry. Then, using the same cell, we show the dynamics of exposing the coating to 6.3% (by mass) acetic acid vapour in air at 75% relative humidity. Whereas unprotected lead shows significant corrosion in under 2 h, a ~1.5 μm coating can withstand the acid vapour for up to 7 h. However, some coatings fail much sooner but nevertheless still show some residual inhibition. Data are correlated with ex-situ techniques including mass gain measurements.
