Pollution: Turn around 300, turn the wheel direction: Clockwise, pressure: 30N.

Note: For each next step, each sample needs to be cleaned in order to proceed with the next step, which prevents over-heavy and grains from embedding.

　　Four, the first.

♪ The world is so full of shit ♪

Diamond spray/FL: 5 micrometres 420 ml

Time: 5-10 minutes (soft 2-3 sluices)

Oxygen-resistant polishing lubricant

Prevention of over-heating in dryness and humid application of mist-type water canteens during polishing.

Note: The polish is clean and completely wet before it is polished.

　Five, polish two.

1 Exactly flair, import hard back base

Imported Aluminium Oxide Opaque: 0.05 μm

3. Optical oxidizing photo-leaching

Time: 5-10 minutes (soft 2-3 sluices)

There's a fuzzy oxidation layer, which needs to be polished with oxidation, while removing small scratches on the surface.

Prevention of over-heating in dryness and humid application of mist-type water canteens during polishing.

Note: The polish is clean and completely wet before it is polished.

　　6. The polishing of 100X is shown in figure IV, figure V, figure VI, figure VII.

For information, you are welcome to actively provide samples to explore and learn from each other.

　II. WELL DEVICE OF CAR PARTS - GIM PIECE PIECE

Sample test purpose: Welding unit of the car welding site for deep smelting, air hole, defects, weld size, etc. (like car seat, frame, etc.)

The embedding steps are as follows:

1 Embedded (equipment: AHBO)

2- Milling equipment: Infinity-referral gold-phase grinder, 500-turner-hourwise transducing

(b) Depletion materials: Sandpaper 240# 600# 1200# grinding in turn, polished with real velvet, and diamond polished with 3.5 micrometres.

3 Observation equipment: measure microscope systems, with a 4% wiping of several seconds of corrosion before observation, which allows for greater clarity between the base and welding interfaces,Drying with a dryer with a dryer.

The results are as follows:
