Abstract

The invention discloses a method for improving the performance of an Inconel 625 nickel-based powder laser cladding layer. The method comprises the following steps that (1) Inconel 625 nickel-based powder and nano boron carbide are weighed as raw materials for preparing reinforced powder; (2) the Inconel 625 nickel-based powder and nano boron carbide are subjected to ball milling and mixing, and reinforced powder is obtained; (3) the reinforced powder is screened; (4) the screened reinforced powder is dried, and the surface of a workpiece to be cladded is pretreated; and (5) laser cladding is carried out on the to-be-cladded surface of the to-be-cladded workpiece, and then finish machining is carried out. The laser cladding workpiece obtained through the method for improving the performance of the Inconel 625 nickel-based powder laser cladding layer is high in hardness and excellent in abrasion performance, the use performance is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of nickel-based superalloy strengthening, in particular to a method for improving the performance of an Inconel625 nickel-based powder laser cladding layer. Background technique [0002] Nickel-based superalloy Inconel625 is a grade of alloy with a density of 8.4g / cm3 and a melting point of 1290-1350°C. It has excellent corrosion resistance to inorganic acids and has excellent resistance to various corrosive media in oxidizing and reducing environments. Corrosion ability. Alloy 625 exhibits excellent corrosion resistance in many media. Excellent resistance to pitting, crevice, intergranular and erosion in chloride media. [0003] Nickel-based superalloy Inconel625 powder has good cladding performance, and its application field is relatively wide in actual production, and its wear resistance at high temperature is excellent. [0004] However, this alloy has the defect of insufficient hardness. Generally sp...
