The circumferential surface of increment 100 and the top surface of increment 100 are mutually perpendicular to；
According to the height of increment 100, cut the height sample to be tested 200 4mm shorter than 100 height of increment, select four to
Cut four samples to be tested 200 are bonded in increment 100 with double faced adhesive tape or glue after increment 100 is cooling by sample
Periphery four surfaces, and the surrounding outer wall of the plate face of sample to be tested and increment fits closely, and obtains sample increment, sample
The height of sample to be tested 200 is lower than the top surface 2mm of increment 100 in sample；
Using the pointing machine with temperature controlling function, interior chamber size is greater than to the bottom of the sample preparation chamber of the interior chamber size of embedding die
After portion is put into inlay, sample increment is put into, is finally putting into inlay, opens pointing machine, by inlay and sample increment heat
It is set into metallographic specimen.
The mode of original cold inlay production metallographic sample, usually the cold inlay of tester's hand, which makes sample, has
Once disadvantage: 1, different proportion liquid being mixed manually, and ratio, which is not easy to grasp, in sample making course leads to different batches
Sample solidification time and quality it is different.2, manual sample preparation waste time, the temperature that distributes have to tester it is uncertain
Harm.
Metallographic sample inlay refer to specimen size it is too small or it is in irregular shape cause grinding and polishing difficult, just need to inlay
Embedding or clamping can make sample rubbing down convenient in this way, improve the accuracy of working efficiency and experiment.In general, needing to inlay
Embedding sample has following several: tiny machine components, such as complex-shaped and superfine small sample or fine small electronics member device
Part, the sample that workpiece surface decarburization layer tissue and depth need to be protected to measure.Cell piece, welding and backboard in the present embodiment is equal
Belong to small part, just needs to carry out metallographic sample before testing its performance to inlay operation.
The embedding sample not deformed in the case where little suitable for low temperature and pressure of hot insert.Plastics are generally mostly used at present
As inlaid material.Inlaid material has thermosetting property plastics, such as bakelite powder；There are also thermoplastics, such as polyvinyl chloride；In addition also
Condensability plastics, such as epoxy resin reinforcing agent.Bakelite powder is opaque, has various colors, and harder, sample is not easy down
The corrosion resistance at angle, anti-strong acid and strong base is poor.Polyvinyl chloride is translucent or transparent, the corrosion resistance of antiacid alkali
It is good but softer.
The hot method for embedding of metallographic sample provided by the invention, pastes on increment by using by the sample to be tested of preparation,
It recycles and carries out the production method of the embedding metallographic sample of hot insert in the two sides up and down of increment setting inlay, can be rapidly completed thin
The small material such as materials such as welding, backboard and cell piece inlay sample preparation, improve preparation efficiency, ensure that sample to be tested in metallographic
Vertical efficiency in sample causes the exterior appearance of test sample and asking for integrity breaks after avoiding metallographic specimen grinding and polishing
Topic, ensure that the accuracy of test speed and testing result, this is easy to operate, suitable for the preparation demand of a large amount of samples to be tested,
Detection speed and detection effect can be effectively ensured, while the health of operator will not be impacted, there is good reality
The property used.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
