This paper will discuss the research and application of laser processing technology in the surface treatment of locomotive crankshaft forgings.
Laser processing technology is an advanced technology that uses high energy laser beam to interact with material to realize material cutting, welding, surface treatment and other processing processes. Laser processing technology has the advantages of high precision, high efficiency and low cost, which is especially suitable for processing materials with high surface quality requirements.
Application of laser processing technology in surface treatment of locomotive crankshaft forgings
Laser cladding and alloying: Through laser cladding technology, alloy layers with special properties can be formed on the surface of locomotive crankshaft forgings to improve surface hardness, wear resistance and corrosion resistance. At the same time, laser cladding can also be used to repair worn or damaged surfaces and extend the service life of crankshaft forgings.
Laser surface strengthening: Rapid heating and cooling of the crankshaft forging surface with laser can produce high density dislocation and lattice distortion, thereby improving the hardness and fatigue strength of the surface. This laser surface strengthening technology can effectively improve the anti-wear and anti-fatigue properties of crankshaft forgings.
Laser etching and patterning: Through laser etching technology, various patterns and marks can be formed on the surface of the crankshaft forging to improve the beauty and recognition of the product. At the same time, laser etching can also be used to manufacture micro and nano structures to improve the frictional and hydrodynamic properties of the surface.
Laser cleaning: The use of laser energy to remove oil, rust and oxidation on the surface of the crankshaft forgings to achieve surface cleaning. Compared with traditional cleaning methods, laser cleaning has the advantages of high efficiency, environmental protection and no damage.
Advantages and challenges of laser processing technology in surface treatment of locomotive crankshaft forgings
Advantages: Laser processing technology has the advantages of high precision, high efficiency and low cost, which can effectively improve the quality, performance and service life of the locomotive crankshaft forging surface. At the same time, laser processing technology can also achieve non-contact processing, reducing the stress impact on the crankshaft forging itself.
Challenges: The equipment of laser processing technology is expensive and requires professional technicians to operate and maintain. At the same time, in the processing process, how to control the size of the laser energy, action time and uniformity and other parameters, is also a key problem to be solved.
Laser machining technology has wide application prospect and potential in the surface treatment of locomotive crankshaft forgings. Through continuous research and exploration, optimizing process parameters and technical routes, overcoming challenges, and giving full play to its advantages, it is expected to further improve the performance and reliability of locomotive crankshaft forgings, reduce production costs, and provide strong support for the transformation and upgrading of the manufacturing industry.
