With the development of economy and society, science and technology are becoming more and more developed, laser cladding technology has become mature, and renewable energy has been given new missions such as energy saving and emission reduction, control of greenhouse gas emissions, and prevention and control of air pollution. Wind power and hydropower, as pollution-free and pollution-free new energy generation, have made great contributions to the power industry.
In the power industry, electrical equipment has a large distribution range and continuous operation, and its components have a high probability of damage. The components of power generation equipment are subjected to gas, high temperature, high pressure and corrosive media to varying degrees in the working environment. Equipment used for a long time may be partially damaged by aging, such as impellers, water turbines, axles, etc., in wind/hydroelectric power generation equipment. In order to extend the service life of expensive production equipment, surface remanufacturing technology can be used to repair it, especially the blades used in generator sets, which are often very expensive to manufacture. Reinstallation and reuse of repaired blades will greatly reduce the cost of power generation.
Laser cladding technology is an important method of material surface modification technology, laser cladding technology advantages are as follows:
1. Stable quality
It uses a laser beam with high energy density to quickly melt alloys with different compositions and properties on the surface of the matrix, and forms a layer with the same properties on the surface of the matrix. The rapid solidification process of alloy layers with completely different compositions and properties. Laser cladding technology can eliminate the defects such as pores and cracks in the welding process, and ensure the quality stability of repaired components.
2. High precision
The melt layer alloy is self-contained, with compact structure, fine grain, increased hardness and toughness, and greatly improved surface properties. Laser cladding technology can achieve high precision surface repair and ensure that the repaired components meet the design requirements.
3. Wide range of application
Laser cladding technology can be applied to a variety of materials surface repair, such as steel, aluminum, nickel-based alloys, etc.
4. High efficiency
Under the action of rapid heating, the substrate is minimally affected by heat and does not deform. Laser cladding technology allows rapid surface repair, reducing production time and maintenance costs.
Laser cladding technology solves a series of technical problems such as thermal deformation and thermal fatigue damage which are unavoidable in traditional welding and argon arc welding.
Laser cladding has the advantages of low dilution rate, compact structure, good combination of coating and substrate, and reliable use. As far as the application of laser cladding is concerned, it is mainly used in three aspects: first, the surface modification of materials, such as turbine blades, rolls, etc.; Rapid prototyping is the use of metal powder layer by layer sintering superposition, rapid production of models. The use of laser can also repair damaged three-dimensional complex parts, which fully reflects the flexibility and advanced nature of laser remanufacturing technology.
