Technical Advantages
Arc spray (twin wire arc spray) offers high-deposition rates, excellent bonding strength, and lower operating cost.
Key advantages include its ability to create thick, wear-resistant, and anti-corrosive coatings on large surfaces using only electricity and air, without damaging heat-sensitive parts
