1. Technology Overview Laser cladding with tin-based Babbitt alloy powder (SnSb11Cu6) is an advanced surface coating technique that restores worn mechanical components such as journal bearings, bushings, and shaft supports. A high-power laser beam melts the Babbitt powder and fuses it metallurgically with the base material, forming a durable and ...

Piston rod, hydraulic cylinder after a period of working will be pitted, worn, scratched, reducing the working pressure of the hydraulic system. Traditional solutions such as chromium plating will have many disadvantages such as: the plating layer is not more than 1mm, easy to peel off, the adhesion is not ...

 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 ...
