 Coating with Tungsten Carbide (WC) by PTA  or Laser Cladding technology for Spear Head and Nozzle of Hydro-turbine in hydroelectric power plants: Working Condition of Spear Head and Nozzle of Hydro-turbine: Working under very high pressure, it is subject to high wear, corrosion, erosion and cavitation, so coating the ...

In factories, the rotor motor shaft after a period of operation will have a problem of shaft is wear, especially with large engines and rotating at high speed. The restoration of worn and corroded locations is extremely necessary to reduce costs instead of replacing the engine with expensive costs. Our ...



Crankshaft: The crankshaft is the main part with an important role in the engine structure. The crankshaft is the part of the engine that converts the reciprocating motion of the piston into rotary motion. Accordingly, they receive force from the piston to create a torque to produce work to be ...

Pumps, Valves and pipelines often encounter problems such as corrosion, erosion, and wear. Therefore, coating a coating against wear, corrosion and erosion will reduce costs and increase the life of the equipment. With Laser Cladding technology to spray both inside and outside, the coating depends on liquid flow of pumps ...





Hydroelectric equipment often works in harsh environments due to extremely high pressure and great friction with water flow, so ordinary metal components cannot guarantee long-term operation, but must use special alloys.   It is for this reason that it is extremely difficult to repair equipment such as stoppers, injectors, shafts, ...

For the lining of the sliding faces of hydrodynamic bearings, tin alloys are commonly used. An important criterion for the primer is to be applied free of foreign particles, having a higher hardness than the composition used. These unwanted particles can damage the shaft, the bearing as a whole, and ...
