1, surface pretreatment: remove oil, oxide layer and residue on the surface of the inner cylinder to ensure a good combination of cladding material and matrix.
2, choose cladding materials: according to the working conditions and performance requirements of the inner cylinder, choose the appropriate cladding materials, such as tungsten carbide, cobalt-based alloy, nickel-based alloy, etc.
3, laser cladding: The use of high energy laser beam heating cladding materials and matrix surface, the material at high temperature melting and rapid solidification, forming a dense coating.
4, post-treatment: the surface of the cladding after the necessary heat treatment, such as annealing or quenching, to improve the performance of the coating.
5, quality testing: through non-destructive testing, hardness testing, metallographic analysis and other methods to check the performance and quality of the cladding coating.
The metal coating prepared by laser cladding provides higher performance for the workpiece, the main characteristics are as follows:
1, improve performance: laser cladding can significantly improve the wear resistance, corrosion resistance and mechanical strength of the inner cylinder, extend its service life.
2, repair wear: can repair the inner cylinder surface wear or damage, restore its original size and performance.
3, accurate control: laser cladding technology can accurately control the thickness and shape of the cladding layer to ensure the surface quality after repair.
4, reduce the thermal effect: compared with traditional thermal spraying and other processes, laser cladding produces a smaller heat-affected zone, which can reduce the thermal deformation and phase change of the matrix material.
5, a wide selection of materials: can use a variety of cladding materials, according to the specific needs to choose the right material, in order to achieve a good repair effect.
Laser cladding enhanced repair technology shows significant advantages in improving the surface properties and extending the service life of the inner cylinder, especially for applications requiring high wear and corrosion resistance.
