Abstract

The invention discloses iron-based laser cladding powder and a method for laser cladding of powder. The iron-based laser cladding powder comprises, by weight, 0.2-0.4% of C, 0.3-0.5% of Si, 0.5-0.8% of Mn, 13-17% of Ni, 22-25% of Cr, 0.1-0.2 of Ti, 0.4-0.7% of Mo and the balance Fe. The iron-based laser cladding powder and method for laser cladding of powder can improve the oxidation resistance ofproducts, and has good abrasion resistance and working strength.

Description

technical field [0001] The invention relates to the field of household paper, in particular to an iron-based laser cladding powder and a method for laser cladding the powder. Background technique [0002] Laser cladding refers to placing the selected coating material on the surface of the cladding substrate in different ways, and then irradiating it with a laser to make it melt with a thin layer on the surface of the substrate and solidify rapidly to form an extremely low dilution and substrate. Metallurgically combined surface coating can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the base layer, so as to achieve the purpose of surface modification or repair, which not only meets the requirements for the specific performance of the material surface but also saves energy. Lots of precious elements. Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding ha...
