Laser cladding powder on surface of shovel tip of sand collecting hopper of sand removing vehicle

The invention relates to laser cladding powder for the surface of a shovel tip of a sand collecting hopper of a sand removing vehicle. The laser cladding powder comprises the following raw materials in percentage by weight: 42.7% of Ti, 7.5% of Al, 3.0% of Cu, 0.03% of C, 0.1% of B, 0.1% of N and the balance of Zr. According to the Zr-based powder component, a cladding layer formed by the cladding powder basically guarantees the original component proportion of the powder, the thermal expansion coefficient of the cladding layer is increased to be close to a 45 steel matrix through Cu and Al elements, meanwhile, the interface bonding performance of the cladding layer and the matrix is improved, and the powder has a good cladding effect. And a cladding layer structure forms a fine solidification structure due to the supercooling effect of the Cu element component and the heterogeneous nucleation effect of the B element, and meanwhile, a nano hard coherent compound (TiZr) 3Al and non-coherent compounds TiC and T
