Abstract
This study investigated the coating failure of the blades of booster fans for the 200 MW flue gas desulfurization plant. Although the arc sprayed SM8222 have been tried as blade coating materials aimed to apply as alternatives of Metcoloy(R)2 due to better corrosion-erosion resistance but it is failed. Bond strength tests and practical field experiences have demonstrated high velocity oxy-fuel(HVOF) coating method with Diamalloy 3004 as an alternative to Metcoloy(R) 2 arc spray.
