Copper based waterborne wood preservatives increase the corrosion of metals embedded or in contact with the treated wood. We examine wood that was in contact with corroding metal with synchrotron based X-ray fluorescence microscopy (XFM) and X-ray Absorption Near Edge Spectroscopy (XANES) to test if the proposed corrosion mechanism is correct.
Chemically Bonded Phosphate Ceramic coating was investigated in various environments such as inland, beach and salt-fog exposure. After 8-month outdoor testing, the coating was evaluated by visual inspection, coating thickness, adhesion measurement and X-ray diffraction. Long term testing ensued, up to 24 months.
