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 ...

Damage to the drive shaft due to long-term wear is inevitable, but we have a solution to repair it domestically at a much lower cost thanks to modern methods such as Laser Cladding and PTA. . After welding hard alloy, this method also requires special machining solutions to achieve high ...

Currently, to increase productivity, some countries have applied laser heat treatment technology to heat treatment of gears and camshafts. Compared with traditional heat treatment methods, laser heat treatment has the following advantages: – Enhanced hardness, strength, fatigue and wear resistance properties – Achieve higher accuracy, lower energy requirements, thus reducing ...

Laser Quenching is an advanced surface treatment method today, in order to improve the durability of the surface of the part. This technology uses a high-energy polar tube laser beam that delivers Local Energy to heat the part surface. As the laser beams travel along the surface, it heats the ...

Boiler tubes, boiler walls in thermal power plants are always in the harsh environment of high temperature wear and corrosion. Therefore, it is extremely necessary to cover the boiler tubes with anti-wear, chemical-corrosion, and heat-resistant coatings. It can significantly extend the life of boiler tubes, while minimizing severe damage. Laser ...

Laser Cladding or PTA is the most effective repair solution for globe valves. Combining the advantages of both hardness and an arbitrary achievable gloss, this is a very effective solution today.

Main materials: Base material 316L, laser cladding based on NiCrSiBo + V, WC, Co,Ti. Coating hardness 50-65HRC, carbide microscopic hardness > 3000HV. In the galvanizing bath environment, the parts are in the molten metal, so the drive mechanism cannot use conventional bearings, but use bearings and direct drive, so the ...

In the steel manufacturing industry, rolling mill rollers are among the most critical components in the production of both cold rolled and hot rolled steel. These rollers are subjected to extreme working conditions — including high temperatures, high pressures, and intense friction — as they continuously come into contact with ...
