In life, there are nine winding paths between heaven and earth, and there is never a straight path. This is true. Water can finally reach the sea because it keeps turning and moving forward amidst countless mountains and valleys. It is inevitable to encounter difficulties in life and work. Turning a corner and taking a detour is not a solution. Just as we encounter difficult to grind samples during the process of using metallographic sandpaper, it is advisable to consider and learn from others' experiences, or explore new methods. As long as we turn a corner, the environment will revolve around and we will explore better ways to solve the problem, so that difficult to prepare samples are no longer difficult.


Metallographic sandpaper is widely used in the preparation of metallographic samples. Metallographic sandpaper can be used for general metal materials, electronics, composite materials, etc. It is relatively versatile and easy to use. But although metallographic sandpaper is easy to use, it is not omnipotent when encountering certain types of materials, and it will really become ineffective. At this point, it's time to change our approach and prepare using a different method.

    When you encounter a Thermal spraying sample, because it contains many cavities and linear delaminations, the cold inlaid sample needs excellent edge maintenance during preparation. At this time, metallographic sandpaper is not competent. Xiao Bian tells you that you can use a diamond grinding disc, and the effect is great. Edge maintenance and flatness are under control. Give it a try!


When you encounter a hard alloy sample, due to the various very hard phases coated on the surface of the hard alloy, there is one characteristic" Hard&# quo;! Usually, precision cutting saws are used for cutting, and the cutting surface is very flat and generally does not require rough grinding. However, there is no way to use metallographic sandpaper for fine grinding and polishing, even if" Skilled workers; It's no use either. We still need to hire a diamond grinding disc, and we need to use a metal bonded diamond grinding disc to lower one object. If we use it correctly, the effect will not be explained. Give it a try!


When you encounter ceramic samples, due to their hardness and brittleness, there may be pores, and during the preparation process, cracks or grain breakage may occur. Therefore, metallographic sandpaper is almost useless when encountering ceramic samples, as both are almost equally hard. Reluctantly giving way to a hard diamond grinding disc or hard polishing cloth. Give it a try!


That's it. When metallographic sandpaper encounters these types of materials, it's as simple as turning a corner and changing the preparation method. I believe you won't deny my viewpoint.

    When the road is impassable, choose to turn, when the heart is not happy, choose to take a dim view; When the situation gradually fades away, choose freely. Whether it's work, study, or life, constantly write new chapters in life as we move forward and take turns.
