Abstract

The invention discloses a powder metallurgy magnetic ring for a new energy automobile magnetic force water pump and a manufacturing method of the powder metallurgy magnetic ring. The powder metallurgy magnetic ring is prepared from, by weight, 1-10 parts of copper, 1-10 parts of calcium phosphate, 0.5-8 parts of graphite, 0.5-8 parts of ethyltrimethoxysilane, 0.5-8 parts of antimony oxide, 0.5-10 parts of nickel, 0.1-3 parts of niobium, 0.2-3 parts of molybdenum disulfide, 0.05-2 parts of zinc borate, 0.1-5 parts of vinyl trimethoxy silane, 0.05-3 parts of sodium metasilicate, 0.1-5 parts of cobalt oxide and 40-70 parts of iron. Calcium phosphate, graphite, ethyltrimethoxysilane, antimony oxide, molybdenum disulfide, zinc borate, vinyl trimethoxy silane, sodium metasilicate and cobalt oxide are mixed, then, deionized water is added for heating and stirring, heating is performed at high temperature, then, copper powder, nickel powder, niobium powder and iron powder are added for high-temperature treatment, and annealing and discharging are performed to obtain the powder metallurgy magnetic ring. The powder metallurgy magnetic ring is not likely to crack, the magnetic performance is improved, and corrosion resistance and abrasion resistance are achieved. The preparation technology is simple, easy to implement, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of magnetic materials, in particular to a powder metallurgy magnetic ring for a new energy vehicle magnetic water pump and a manufacturing method thereof. Background technique [0002] Soft magnetic materials are magnetic materials with low coercive force and high magnetic permeability. Soft magnetic materials are easy to magnetize and demagnetize, and are widely used in electrical and electronic equipment. The most widely used soft magnetic materials are iron-silicon alloys (silicon steel sheets) and various soft ferrites. With the continuous development of the automobile industry, the penetration rate of environmentally friendly, energy-saving and emission-reducing, green new energy vehicles is increasing year by year, and the demand for soft magnetic materials is also increasing steadily, especially for electrical appliances such as motors and controllers for new energy vehicles. The market size of the ...
