摘要（英）：

The invention discloses a laser cladding material, a laser cladding method and spring steel components and parts repaired by the method. The laser cladding material comprises a bonding layer material and a functional layer material. The bonding layer material is composed of the following components in percentage by mass: 40-48% of Ni, 0.5-0.7% of B, 0.5-1.0% of Si, 0.3-0.4% of C and the balance Fe; the functional layer material is composed of the following components in percentage by mass: 9-15% of Ni, 1.0-1.5% of WC, 0.5-0.7% of B, 0.5-1.0% of Si, 0.3-0.4% of C and the balance Fe. The laser cladding material is designed by gradient cladding, so that the bonding force between a cladding layer and a substrate is improved, and the frictional wear resistance of the material is improved. The laser cladding material is suitable for a laser treatment process for preparing a wear-resistant coating by a spring steel material and is suitable for repairing failed wear-resistant components and parts in size of spring steel.
