AI Technical Summary
Centrifugal pump components are prone to corrosion and damage when in contact with corrosive media, leading to leakage, performance degradation and shortened service life. Furthermore, existing anti-corrosion processes are cumbersome, time-consuming and costly.
A composite anti-corrosion coating is formed on the surface of the flow-through components of the centrifugal pump, including a zirconia ceramic film, a silane coating, and an electrophoretic coating. The coating is formed layer by layer through zirconia treatment, silane treatment, and electrophoretic coating processes to improve adhesion and corrosion resistance.
It significantly improves the corrosion resistance of the centrifugal pump's flow components, extends their service life, reduces maintenance costs, and ensures equipment stability and environmental safety.
