The conductive silver layer prepared on the aluminum surface can effectively reduce its contact resistance and improve its conductivity. Electroplated silver is the most common way to prepare conductive silver layers, but the electroplated...

Overflow components in water conservancy equipment, such as turbine blades and impeller nozzles, are often subject to erosion by sand and erosion, which causes metal loss on the surface of the overflow components, which causes vibration and...

The cavitation failure of the overcurrent components in the parts of the hydropower unit is the main failure mode. The area to be repaired mainly occurs at the water inlet side, and the local thickness is large, and the amount of cavitation...

Thrust tile repair Because of the long-term use, there are erosion spots of different sizes and depths on the surface of the thrust tile. Thrust tile defects will bring hidden dangers to the safety, stability and operation of the unit. Firs...

Wheel room steel plate repair The lower ring steel plate of the runner room is close to the turbine blades, and is affected by pressure pulsations and cavitation. After long-term use, serious cavitation pits and cracks will occur. Tradition...
