Embodiment 1

[0038] The high-purity electrolytic nickel plate is used as the anode, and the 1Cr18Ni9Ti stainless steel sheet is used as the cathode. First, the composite electroplating solution is formed by mixing the dispersed particle suspension and the basic electroplating solution. Wherein, the dispersed particles are selected from ZrO 2 and La 2 o 3 Mixture of nanoparticles. ZrO 2 The average particle size D of the nanoparticles 80 58nm; La 2 o 3 The average particle size D of the nanoparticles 80 206nm. ZrO 2 with La 2 o 3The weight ratio of nanoparticles is 2.5:1. The dispersed particle suspension further comprises polyacrylic acid (PAA) with a number average molecular weight Mn of 7200. Based on the volume of the composite electroplating solution, the amount of dispersed particles is 14g / L; the amount of polyacrylic acid is 0.2g / L. The dispersed particle suspension is obtained by ball milling; the process parameters are: the ball-to-material ratio is 5:1; the solid co...

Abstract

Disclosed is a nickel-based wear-resistant alloy, which is obtained by electrodeposition from a composite electroplating solution mixed with a dispersed particle suspension and a basic electroplating solution. The dispersed particles are selected from ZrO 2 and La 2 o 3 Mixture of nanoparticles. Based on the weight of the nickel-based wear-resistant alloy, the nickel content is 70.0‑76.0wt%; the tungsten content is 18.0‑22.0wt%; the phosphorus content is 3.0‑5.0wt%; ZrO 2 The content is 2.0‑4.0wt%; La 2 o 3 The content is 1.0-2.0wt%. Both the friction coefficient and the wear rate of the above-mentioned nickel-based wear-resistant alloy are lower than those of similar nickel-based alloys in the prior art.

Description

technical field [0001] The invention belongs to the technical field of metals and alloys, and relates to a high-performance nickel-based alloy, in particular to a high-performance nickel-based wear-resistant alloy. Background technique [0002] Among all kinds of mechanical equipment, instruments and meters and many key components, metal materials are widely used as a class of materials, which need to work under high temperature, high speed and corrosive conditions. Therefore, it is urgent to improve the corrosion resistance, heat resistance and wear resistance of metal materials so that they can work stably for a long time. Among them, wear resistance is a particularly important indicator. [0003] Although many alloys can meet the above requirements, the production cost is high and the preparation process is complicated, which makes these materials have great limitations in the application of equipment or parts manufacturing. Since the wear of materials starts from the s...
