Metalized corrosion control coatings applied with low energy “Big Wire” arc spray systems are significantly reducing the application costs of long life coatings. The increased deposition rates and the improved deposit efficiencies achieved with twin wire 3/16” (4.8MM) feedstock over 1/8”(3.2MM) feedstock significantly reduce coating application costs. Arc sprayed “Big Wire” metalized coatings have evolved from early efforts of field production personnel to reduce coating costs. Low energy, high deposition twin wire arc sprayed coatings are gaining importance as a viable competitive long life, low maintenance coating. Metalized coatings have the additional benefit of being Volatile Organic Compound (VOC) free.
