Description

Technical Field

[0001] The utility model relates to the technical field of metallographic testing, in particular to a metallographic analysis auxiliary film. Background Art

[0002] Microstructure analysis of metal materials is a key means to deeply explore the internal structure of materials. This process usually relies on various types of equipment to observe the structure. These devices have different magnifications, so the organizational information obtained is also unique. If the microstructure observation equipment is classified according to magnification and operation complexity, it can be divided into metallographic microscopes, scanning electron microscopes, and transmission electron microscopes.

[0003] Metallographic microscopes are widely popular in enterprises and universities due to their relatively low cost and convenient operation. However, their magnification is relatively limited, and they cannot be combined with energy spectrum equipment like scanning electron microscopes and transmission electron microscopes to analyze micro-area components. Therefore, if characteristic structures are observed under a metallographic microscope, further analysis of the morphology or composition needs to be performed under a scanning electron microscope.

[0004] At present, the common operation process is to first use a metallographic microscope to make a preliminary observation of the microstructure, identify the characteristic structure, and then manually mark a macroscopic characteristic area on the sample. Subsequently, the manually marked macroscopic characteristic area is further observed under a scanning electron microscope, and the characteristic structure is located, so as to further magnify and analyze the characteristic structure or perform energy spectrum analysis. However, this operation method has significant problems: the characteristic structure magnified hundreds of times under a metallographic microscope is difficult to accurately correspond under the macroscopic mark, especially when looking for these characteristic areas under a scanning electron microscope, the difficulty of finding is increased due to inconsistent image contrast, which is not only inefficient, but also wastes the precious machine time of the scanning electron microscope, and increases unnecessary usage costs. Utility Model Content

[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way serves as any limitation to the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0032] As Figures 1 to 5 shown in the figure, an embodiment of the present utility model provides an auxiliary film for metallographic analysis, including a grid coordinate film 100. The grid coordinate film 100 is used to adhere to the observation surface of a metallographic sample 400. The grid coordinate film 100 is a grid-like hollow structure. The grid coordinate film 100 includes a plurality of intersecting solid structure lines 110. The plurality of solid structure lines 110 divide into a plurality of hollow observation holes 120. The observation holes 120 expose the observation surface. Positioning coordinates 130 are marked on the solid structure lines 110. The positions of each of the observation holes 120 are located respectively through the positioning coordinates 130.

[0033] Adopting this solution, the observation surface of the metallographic sample is divided into a plurality of observation areas through the grid coordinate film 100, that is, the positions corresponding to the plurality of observation holes 120. And the positions of each observation hole 120 and the observation area can be accurately distinguished through the positioning coordinates 130 on the solid structure lines 110. After observing the characteristic tissue of the metallographic sample 400 under a metallographic microscope, the position of the characteristic tissue can be recorded through the coordinates. Then when observing the metallographic sample 400 under a scanning electron microscope, the position of the characteristic tissue can be quickly found through the recorded coordinates, thus realizing rapid observation, improving the analysis efficiency and reducing the use cost.

[0034] Among them, the plurality of solid structure lines 110 are straight lines arranged in rows and columns, and the plurality of observation holes 120 are rectangular holes arranged in rows and columns. Through the above settings, the plurality of observation holes 120 are regularly distributed, which is convenient for regularly dividing the observation surface, convenient for setting the positioning coordinates 130 and finding the positions.

[0035] As Figure 2 and Figure 4 shown in the figure, each of the solid structure lines 110 is divided into a plurality of line segments. At least a part of the line segments are marked with separate positioning coordinates 130. Each of the observation holes 120 is surrounded by four of the line segments. In this way, the observation holes 120 at the corresponding positions can be located through the positioning coordinates 130 on the line segments.

[0036] In Figure 4 , (1, 1), (1, 2), (2, 1), (2, 2) are the schematic diagrams of the positioning coordinates 130.

[0037] Among them, the grid coordinate film 100 is made of an opaque conductive material. By using an opaque material, the positions of the solid structure lines 110 and the observation holes 120 can be clearly seen. The grid coordinate film 100 adopts a conductive material to meet the use requirements of a scanning electron microscope.

[0038] Specifically, the material of the grid coordinate film 100 is indium tin oxide or polyethylenedioxythiophene.

[0039] In this solution, the line width of the solid structure line 110 of the grid coordinate film 100 is 0.01 mm to 1 mm. The specific line width value is set according to the usage requirements, and it is necessary to ensure that the solid structure line 110 is not easily broken and does not overly block the observation surface. The solid structure line 110 can be processed by laser etching to ensure accuracy.

[0040] Among them, the area of the observation hole 120 is 0.0001 mm 2 ~2 mm 2 . The specific size of the observation hole 120 is set according to the usage requirements.

[0041] In this solution, the thickness of the grid coordinate film 100 is 0.01 mm to 0.5 mm.

[0042] Furthermore, the metallographic analysis auxiliary film also includes a first protective film 200 and a second protective film 300. The grid coordinate film 100 is located between the first protective film 200 and the second protective film 300. The side of the first protective film 200 facing the grid coordinate film 100 has an adhesive material and is bonded to the grid coordinate film 100. The side of the grid coordinate film 100 facing the second protective film 300 has an adhesive material and is bonded to the second protective film 300.

[0043] The first protective film 200 and the second protective film 300 can protect the grid coordinate film 100. When using the grid coordinate film 100, the first protective film 200 and the second protective film 300 are removed.

[0044] Among them, the first protective film 200 and the second protective film 300 are made of transparent materials. This makes it convenient to determine the position of the grid coordinate film 100 and the direction of the solid structure line 110 during pasting.

[0045] During use, first tear off the second protective film 300, and stick the first protective film 200 and the grid coordinate film 100 together on the observation surface of the metallographic sample 400. The grid coordinate film 100 covers the entire observation surface. Then tear off the first protective film 200 from the grid coordinate film 100, and only leave the grid coordinate film 100 on the sample. Then place the sample under a metallographic microscope to observe the tissue. After finding the characteristic tissue that needs further analysis, record the coordinates of the grid where the characteristic tissue is located. Then place the sample under a scanning electron microscope, and quickly locate the characteristic tissue according to the recorded coordinates and conduct further analysis. In this way, it is possible to realize that the tissue obtained under a metallographic microscope can also be observed and analyzed in situ under a scanning electron microscope.
