Laser cladding technology began to emerge in the mid-to-late 20th century. Laser cladding technology is a relatively advanced technology to improve the surface of the workpiece and has developed rapidly in industry. Laser cladding technology uses laser to blend metal powder and substrate.
Because laser cladding technology is quite special, it has attracted widespread attention from the scientific and technological community, and the industry has also paid attention to this technology. The application scope of laser cladding is gradually expanded. Some cutting-edge workpieces are generally powerless in traditional processes, and laser cladding technology is highly valued in various industries.
At present, the application fields have covered the fields of automobile machinery manufacturing, mold manufacturing, aviation, etc.
Compared with traditional processes, laser cladding technology has the following advantages:
1. The surface of the process is flat and the workpiece processing volume is very small in the later stage, which saves the workpiece processing cost for the enterprise, can strengthen or repair some high-precision parts, and the chance of workpiece deformation poles are small.
2. The dilution rate of laser cladding is relatively low, and the coating performance of the workpiece can be fully guaranteed.
3. The laser cladding layer has relatively dense structure, and the workpiece has relatively few defects.
shortcoming:
1. High cost, complex control of precision but special performance.
2. The equipment is relatively expensive.
3. The workpiece quality is not stable and may not meet the accuracy required by users. This is also the reason why laser cladding technology is not widely used in the industry.
Compared with traditional restoration industrial technology, the advantage of laser cladding restoration technology is that it plays an extremely important role in the development of the circular economy. For ship repair, it saves material consumption and premiums for ship repair, which is in line with my country's national industrial development policies and deserves active promotion and application.
