TongBall's plasma-sprayed ceramic blades deliver exceptional protection against wear, corrosion, and high-temperature oxidation in demanding industrial environments. Engineered with dense Al₂O₃, Cr₂O₃, or ZrO₂ coatings, these blades achieve surface hardness exceeding HV 1200 while maintaining excellent thermal stability up to 900°C. The advanced ceramic coating effectively resists particle erosion, chemical attack, and material buildup, making them ideal for applications in chemical processing, power generation, and mineral handling industries. By significantly extending blade service life and reducing maintenance frequency, our ceramic-coated blades provide a cost-effective solution for critical rotating equipment including fans, pumps, and mixers.
