Hello everyone! I am Kemai Testing Editor Coco.


A few days ago, I posted about the metallographic cutting pieces used for cutting pearlite steel metallographic samples, as well as the relevant plans for polishing cloth. Many friends came to ask Coco how to choose metallographic consumables to prepare pearlite steel samples?

Yes, there are so many metallographic consumables such as cutting, inlaying, and polishing. What kind of material can be chosen to quickly and well prepare high-quality pearlite steel metallographic specimens?


The editor has summarized his experience through experiments as follows, for your reference!


Experimental equipment used: grinding wheel metallographic cutting machine, single cylinder hot pressing inlay machine, automatic metallographic polishing machine


Selected metallographic consumables:


1、 Cutting: We have selected HRC30-45 grinding wheel cutting blades with a hardness of QMAXIS from the United States. There are many models available, and the diameter and thickness can be selected based on the size of the sample being cut. What do I choose? A 10 inch (254mm) resin bonded grinding wheel cutting blade with a thickness of 1.5mm, odorless and more environmentally friendly.


2、 Embedding: We have selected EpoPowder epoxy resin powder from QMAXIS in the United States, with no significant difference in particle or powder.


3、 Grinding and polishing: Diamond grinding discs, polishing fluid, polishing cloth, etc. from QMAXIS, USA were selected, and the list is as follows:

Of course, QMAXIS can also be used for other auxiliary materials, such as cutting coolant, polishing cooling lubricant, etc. If there are other brands available in the laboratory, they can also be used. As long as the quality of the product is qualified, it will not affect the quality of sample preparation, so it is good not to waste it.

The metallographic consumables were selected correctly, and the sample preparation was very handy. It was quickly prepared, look! The structure of pearlite is clearly visible under the microscope! Is it more like an aerial photo of the turbulent sea!? pretty I believe you will do better in preparing pearlitic steel specimens using metallographic consumables selected in this way.


Friends, if you need a detailed understanding of the preparation method of pearlite steel, you can directly contact the application engineers of pulse detection, who are more professional than the editor.
