Laser Cladding is an advanced surface restoration and strengthening technology. It utilizes a high-energy, focused laser beam to melt metallic powder and fuse it with the base material surface. This process creates a dense, wear-resistant coating with excellent bonding and mechanical properties. Laser cladding is especially suitable for components subject ...

Why is rotor repair necessary? The rotor is the central rotating component of a hydro generator, operating under heavy load and in harsh conditions. Over time, it often experiences: Surface wear at bearing or journal areas Cracks, pitting, or scratches due to friction and temperature Dimensional deviations affecting dynamic balance ...

Piston heads made from aluminum alloy are widely used in automotive engines, compressors, and industrial equipment due to their lightweight, high thermal conductivity, and excellent heat resistance. However, during operation, piston heads are prone to wear, cracks, and deformation, which can negatively impact engine performance. PHUONGDONG INDUSTRY offers a high-precision ...

Laser cladding for inner bore repair of gear shafts (Ø30mm) is an optimal solution to restore worn, cracked, or deformed surfaces caused by industrial operation. At PHUONGDONG INDUSTRY, we apply advanced laser cladding technology to precisely restore the inner bore of gear shafts. The process creates a high-hardness alloy layer ...

Laser Cladding is increasingly used in the repair and surface enhancement of industrial components. For hollow parts such as cylinder bores, internal surface restoration presents a number of technical challenges due to space limitations and a high risk of thermal distortion, cracking, and coating delamination. Challenges in Internal Surface Cladding ...

1. Technology Overview Laser cladding with tin-based Babbitt alloy powder 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 uniform ...

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 ...
