Embodiment 1
[0016] Embodiment 1: organization is the preparation of the longitudinal section thin film sample of pure ferrite
[0017] (1) Cutting the sample: the sample structure is pure ferrite, the aluminum oxide 40A15 cutting wheel is selected according to the microhardness value of the sample, the preset feed speed is 0.060 mm / s, the cutting load is adjusted to medium strength, and the cutting wheel speed is adjusted to 2500 rpm. The filaments were cut into three small sections of 2.8 mm, 2.9 mm, and 3.0 mm in length.
[0018] (2) Grinding samples: use flat frosted glass as the grinding and polishing plane, press a filament with a square rubber, grind a plane on 800# water sandpaper, and grind the second and third filaments in the same way. Silk. Stick the flat side of the three filaments side by side on the 10x20mm ground glass with 502 glue. After the sample is firmly pasted, use 800# water sandpaper to grind the opposite side on the flat ground glass. The two planes of the sampl...
