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 ...

Fan blades in turbines, compressors, and industrial ventilation systems operate in harsh environments, constantly exposed to high temperatures, dust, and corrosive gases. Over time, this causes significant erosion and corrosion on the blade surface. These components are often thin and delicate, making them highly vulnerable to warping or distortion during ...

Laser heat treatment, also known as laser hardening, is an advanced surface treatment technology that uses a high-power laser beam to locally heat the surface of metal materials to hardening temperature. Thanks to the extremely rapid self-quenching ability of the base material, the surface layer becomes hardened without altering the ...

Laser Hardening is an advanced heat treatment technology that uses a high-power laser beam to locally heat the surface of a metal component to its hardening temperature, followed by self-quenching using the material’s own mass. This process creates a high-hardness surface layer, significantly improving wear resistance while avoiding distortion or ...

Repair the roller shaft by Laser Cladding is the most advanced technology today. It is quick to repair, and saving cost and time. In addition, depending on the working conditions, it is possible to choose suitable powders to increase service life, resist wear and corrosion… We specialize in providing welding, ...

Bearing-mounted shafts are often quite diverse in terms of materials and sizes. After the working process, the shafts usually will be abrasive, scratched the surface due to disassembly, or chemical reaming. Solution: coating the suitable material, then machining to become the original size. Currently, Laser Cladding technology is the most ...
