Problems solved by technology

The reason why nickel-based powders are different from iron-based and cobalt-based powders is that most of the repaired nickel-based superalloys use γ' formed by nickel and aluminum elements as the main strengthening phase, and iron-based and cobalt-based powders will affect the composition of the repaired area. Causes significant changes that affect the overall performance of the repaired artifact

Abstract

The invention relates to the field of laser cladding materials, and discloses nickel-based multi-component laser cladding powder. The powder comprises, by mass, 10-25% of Fe, 6-15% of Al, 1-5% of TiB2, 0.5-1.0% of Dy and the balance Ni. The invention further discloses a laser cladding method for the powder. The method comprises the steps that the nickel-based multi-component laser cladding powder and absolute ethyl alcohol are mixed, the surface of a cladding base material is evenly covered with the mixture, drying is carried out after roll pressing, a preformed layer is formed, and the cladding layer can be obtained through laser cladding. By means of the technology, the crack-free laser cladding layer can be obtained, the hardness is high, the cost is low, the fusion degree is improved, the strength and plasticity are ensured, and the powder is suitable for repair machining of various parts.

Description

technical field [0001] The invention relates to the field of laser cladding materials, in particular to a nickel-based multi-component laser cladding powder and a method for laser cladding the powder. Background technique [0002] With the rapid development of laser technology, it is playing more and more important roles in the field of material processing. As a kind of laser processing technology, laser cladding has the advantages of fast forming speed, small processing area and high control precision. Surface repair and surface modification of material workpieces are playing an increasingly important role. Laser cladding process melts specific powder or wire on the surface defect of the workpiece, so that the defect surface and molten powder re-solidify and crystallize, obtain a complete surface structure, and restore the performance of the workpiece. In addition, laser cladding can continuously melt and crystallize specific powder on the surface of the workpiece to obtai...
