| Abstract |
The protective coating of LED lighting plays an important role especially in marine corrosive environment. In this study, the aging and corrosion characteristics of coating were measured by AC impedance method on three samples with coatings of different corrosive resistance. The environmental accelerated test conditions of coating were according to NORSOR M-501 standard. Also the corrosion properties were recorded after each cycle on the samples of a coating with or without UV irradiation. After 5 cycles, the corrosion resistance of the sample was evaluated in the order of PVDF > Powder coatingⅡ > Powder coatingⅠ. The sample irradiated with UV showed the corrosion rate of 10∼30% faster. For the case of powder coatingⅠ&Ⅱ with UV, impedance characteristic decreased to or less after 5 cycles showing that maintenance is already necessary. |
