Abstract

The invention discloses a preparation method of an electrogalvanizing layer doped with nanometer particles. Each liter of an electroplating liquid comprises the following components: 8-15g of zinc oxide, 80-150g of sodium hydroxide, 150ml of a ZN-500 brightening agent, 1-3ml of a ZN-500 low-area dispersing agent, 1ml of a ZN-500 impurity removing agent, 1ml of a ZN-500 water treating agent, 1.0-1.5g of nanometer titanium dioxide particles, and the balance of deionized water. According to the preparation method of the electrogalvanizing layer doped with the nanometer particles, disclosed by the invention, through the addition of the nanometer titanium dioxide particles, the fine degree of the crystallization of a galvanizing layer can be effectively improved, so that the galvanizing layer and a substrate have good binding force, and the corrosion resistance of the galvanizing layer and the wear resistance of the galvanizing layer are improved significantly; therefore, the thickness of the galvanizing layer can be effectively lowered, and the surface treating cost is reduced; in addition, the preparation process of the electrogalvanizing layer and the production process of the electrogalvanizing layer are environment-friendly, non-toxic and harmless.

Description

technical field [0001] The invention relates to a preparation method of a nano particle-doped electro-galvanized layer, and belongs to the technical field of nano-powder doped metal coating technology. Background technique [0002] NdFeB magnets have excellent magnetic properties, but because NdFeB magnets are composed of multiple phases, the potential difference of each phase is relatively large, especially the Nd-rich phase has a low potential, which is prone to intergranular corrosion, resulting in NdFeB magnets The corrosion resistance of the magnet itself is very poor; moreover, the NdFeB permanent magnet is produced by the powder metallurgy process, the actual density of the product cannot reach the theoretical density, and there are tiny pores inside, and the rare earth elements in the atmosphere are susceptible to oxidation and corrosion, destroying the alloy components . In order to avoid electrochemical corrosion and oxidative corrosion of NdFeB permanent magnets ...
