Figure 9
Comparison of different sealed systems used at the LMC Station, after 41 months of exposure (a) Thermal sprayed coating of zinc by flame process (wire), sealed with wash primer 1 (173 μm). (b) Thermal sprayed coating of zinc by the electric arch process, sealed with wash primer 1 (264 μm). (c) Thermal sprayed coating of zinc by electric arch process, sealed with phenolic (261 μm) (66 months of exposure). (d) Thermal sprayed coating of aluminum by electric arch process with phenolic (261 μm). (e) Thermal sprayed coating of aluminum by electric arch process, sealed with wash primer 1 (251 μm). (f) Thermal sprayed coating of Zn/Al by the flame process, sealed with wash primer 1 (345 μm).
