The inside of the bearing steel pipe is an isometal-gold-phased sample method

The main processes in the GCr15 bearing steel tubes are the contour of the heated duct, thermal piercing, the spherical retreat, acid lubrication, cold-deeping, the retreating, the correction, etc.

Anomalous is found when the coatings of the processing axle are taken from the gutter (figure 1.6-1). In the case of the gutter, the steel tube matrix is found to be woven with an isometal, which is separated from the aerometal, which is not eroded by the ethanol solution of nitrate (figure 1.6-2), which is seen with a permutation of the photo-high view, and is seen with microinterferometry, which shows a coarsed crystal fray (figure 1.6-3-1.6-4), which can be considered to be a material with a higher alloy content.

Based on the processing of the axle bearing steel pipes, the degree of insulation of the heifer and the structure of the heifer, it is determined that the result is the break-up of the top of the heated piercing.

The following are the products that will be used for gold phase:

1. FY-QG-65, a Fuyunkin co-moder, cut the sample gold and cut down a small piece, horizontal or vertical, as required by the sample, to facilitate mosaicing.

II. Kim Co-simworks:

Fuyun materials gold-specific sandpaper: 230mm diameter without glue 600# 1200# 2500#   

III. LEAVE THE FIELDS OF THE KING PHOTOS:

Fuyun materials gold-phased photo fabric: 230 mm in diameter velvet/splendon

Fuyun materials, Fresco-Frestilt Spraying: 1/3 micrometre

Fuyun machine: manual in no-extreme-speed grinder

Pressure: Fixed, neutral, stable, without too much pressure.

Time: 2-5 minutes, whichever is the same, the scratches of the thin sandpaper are almost removed.

Rotation speed: 200 turns

Raarboard direction: Clockwise

During polishing: The polished rags need to be immersed early, the polished fluid is down in the centre position and handwashing is added to its lubrication.

Pour: A little bright, no scratches, and can move on.

During polishing: The polished rags need to be immersed early, the polished fluid is down in the centre position and handwashing is added to its lubrication.

Pouring: The brightness is very high.

Corrosion observation:

Gold-photo microscope (magnification multiple: 50X, 100X, 200X, 500X, 1,000X)

The following are used for corrosive reagents:
