Embodiment 1
[0094] (1) Nd, B, Co, Cu, Al, Zr, Fe raw materials according to the mole percentage of Nd 25.8%, B 0.98%, Co1%, Cu 0.27%, Al 0.18%, Zr 0.4%, Febal ratio, the total alloy The mass is 5kg, put into the vacuum induction melting furnace at the same time, through the process of charging - vacuuming - preheating - argon filling - high power smelting - low power stirring - casting and other processes, the smelted alloy liquid (copper roller adopts cooling water Cooling, the rotating speed is about 35-50 rpm) to make a well-crystallized sheet with a thickness of about 0.3-0.4mm, and select an alloy quick-setting sheet with a smooth performance, uniform thickness, and bright white color to prepare powder for use.
[0095] (2) Put the selected quick-setting tablets into the special hydrogen crushing furnace, and carry out coarse crushing through positive and negative pressure detection-hydrogen absorption-heating-vacuum dehydrogenation-cooling-out of the furnace, etc. In nitrogen-protec...
Embodiment 2
[0109] Steps (1)~(5) are identical with steps (1)~(5) in embodiment 1;
[0110] The difference is as follows:
[0111] (6) Use gasoline and a NaOH solution with a concentration of 2mol / L to remove the oil stains on the surface of the small cylinder successively, and then place it in a sandblasting machine for surface derusting and descaling treatment (the diameter of the steel shot is: 0.1~ 0.3mm, sandblasting time: 20 minutes). Afterwards, the surface of the small cylinder is polished on a cylindrical grinder (polishing time: 30 minutes), and finally the polished small cylinder is placed in a mixture of absolute ethanol and acetone, and the surface of the magnet is further decontaminated under the action of ultrasonic waves Processing (ultrasonic frequency: 100 Hz, cleaning time: 10 minutes), take out the small cylinder and let it dry naturally at room temperature for later use.
[0112] (7) While cleaning the surface of the magnet, get sodium silicate and add zinc silicate...

[0118] Steps (1)~(5) are identical with steps (1)~(5) in embodiment 2;
[0119] (6) Use gasoline and NaOH solution with a concentration of 2% to remove the oil stains on the surface of the small cylinder after slicing, and then place it in the sandblasting machine for surface derusting and descaling treatment (the diameter of the steel shot is: 0.1 to 0.3 mm, sandblasting time: 30 minutes). Afterwards, the surface of the small cylinder is polished on a cylindrical grinder (polishing time: 40 minutes), and finally the polished small cylinder is placed in a mixture of absolute ethanol and acetone, and the surface of the magnet is further decontaminated under the action of ultrasonic waves Processing (ultrasonic frequency: 100 Hz, cleaning time: 20 minutes), take out the small cylinder and let it dry naturally at room temperature for later use.
[0120] (7) While cleaning the surface of the magnet, get sodium water glass and add zinc silicate to fully mix (zinc silicate accounts...
