ITALIAN HOME PAGE COMPANY PRODUCTION QUALITY APPLICATIONS NEWS WHERE WE ARE CONTACTS MKGT and communication The metallographic analysis laboratory: the solution at the heart of the metal published on Tuesday 12 November 2013 Contacting a metallographic analysis laboratory can be useful both to a company and to a private individual who wants to know what is hidden inside a particular metal, especially when it is used often or comes into contact with delicate surfaces. Thanks to this type of test, it will be possible to discover the structure of the metal, its composition and the physical, chemical and technological properties so as to also be able to see if there are impurities or defects inside the metal. For a correct metallographic analysis, two types of microscopes are used: the optical microscope and the electron microscope. The optical microscope allows you to magnify the surface up to 450 X and enter the heart of the metal. The first thing to do is to polish the metal perfectly, which will have standard dimensions of about a few centimeters. When cutting the piece of metal to be analyzed, however, it can happen that it overheats due to rubbing and loses some of its properties. It is therefore advisable to always use a metal that is already of the right size or try to cut it with the aid of a refrigerant substance. As for polishing, however, the surface of the metal is smoothed through a horizontal sander, to transform it into a smooth surface without any trace of roughness. After having polished the metal, we then move on to the actual metallurgical analysis which also serves to understand the type of quality of the metal. A drop of chemical reagent is poured, which can be Nital, Hydrochloric Acid, Glycerinized White Spirit, on the metal and its composition and degree of purity are examined. To examine the crystalline structure of the metal, however, it is necessary to use the anode-cathode solution which will allow to analyze the heart of the metal.
