Information

Laser cladding technology can significantly improve the wear resistance, corrosion resistance, heat resistance and oxidation resistance of metal surfaces. With surfacing welding, thermal spraying, electroplating, etc. According to the initial supply state of the cladding material, the cladding material can be divided into powder, paste, filament, rod and thin plate. Among them, the most widely used is the powdery material. According to the material composition, laser cladding powder materials are mainly divided into metal powder, ceramic powder and composite powder. Among the metal powders, there are more researches and applications of self-fluxing alloy powders.

 

For a reasonable cladding material/base metal matching system, the best cladding layer performance can be obtained by optimizing the laser cladding process. Therefore, since the 1980s, the laser cladding technology has received extensive attention at home and abroad, and has been applied in many industrial fields.

 

Laser cladding inpower Industry`sapplications

 

Under the conditions of high-speed operation, the rotor journals of steam turbines in power plants have abrasion problems. In addition, the final and last-stage blades of steam turbines often suffer from cavitation under long-term high-temperature environmental working conditions. The steam turbine is a large-scale equipment and is not easy to transport, so laser in-situ repair technology with high reliability is required

 

With the rapid development of my country's nuclear power industry, the requirements for structural materials of nuclear reactors are getting higher and higher. Structural parts in the nuclear power industry are subject to many adverse effects such as high temperature, corrosion, and oxidation due to the working environment and media. Therefore, some core components have always been imported from abroad. At this stage, the development of my country’s nuclear power industry has entered a fast lane, and the requirements for localization of core components are becoming strongerUsing laser cladding technologyis able toThe nuclear power steam generator (SG) alloy 690 heat transfer tube was strengthened, and the laser cladding technology was used to prepare the zirconium alloy accident-tolerant fuel cladding (ATFC).
