Renewable energy sources are an increasingly important part of the country’s energy portfolio and wind power is one of the significant sources. Wind mill component corrosion is one of the first maintenance concerns to be considered.
Hot dip galvanizing, followed by painting are older practices used by wind mill manufacturers to prevent corrosion, the process is limited and paint sometimes peels off during assembly.
Thermal spray coating has become a suitable solution to apply on these wind mills and components.
Some benefits include equipment that is portable, so both on-site and in-shop services are possible; no chemical treatment is involved, so there is no environmental hazard, coated components can readily be used just after the coating process is completed; materials can include zinc, aluminum or Zn-Al alloys; the thickness of the coating can be varied from 20 microns to 1 mm; and there is no harm if any paint or sealant is applied as post treatment.
