Composite coatings of gold slice measurements and measurement solutions

I. MEDIUM PLALLING DEVICES IN VARIOUS PARTS - GLON PIECE PIECES

Sample Engineer: Zhang Jin-in

TEL：15990346569

E-mail：ren@fulwintt.com

Materials: base-based rough, coated soft metal materials

Hardness: Softness

Detective subcategories: observation of plating defects, e.g. drum packs, gas holes, impurities, etc.

2. The embedded images are shown below

3 Grinding: Golden-skin-skin-skin-skin-skin-skin-skin-skin-skin-slinging machine Brand: Fuyun

Grid: 240# 600# 1200#  

Turn speed: around 300.

Turn direction: Clockwise

Pressure: 30N.

Time per sandpaper: about one minute (striped evenly, no multiples present)

Grid: 4,000# Brand: Fuyun ♪ And grind along one side ♪

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 Brand: Fuyun

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.   

1 Exactly flair, import hard back base

2. Imported process aluminium oxide polishing: 0.05 μm  Brand: Fuyun

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.

Five, polish two.

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: AHB)  Depletion material: hot mosaics, just plain hot mosaics)

2. Griding equipment: non-extremely-referred gold-phase grinder Turn speed 500 and clockwise.

Depletion: Sandpaper 240 # 600 # 1200 # The gravitation is then velvet, and the lumber is 3.5 micrometres.

3 Observation equipment: Measurement of microscope systems, with a 4 per cent wiping of several seconds of corrosion before observation, which allows for greater clarity between the base and welding interfaces, and drying with a blow-dryer with alcohol.

The results are as follows:
