For metallographic practitioners, when they see a beautiful metallographic photo, they always can't let it go, and they can't help but sigh that other people's microscopes are different. However, this is not the case. The wonderful photos are first polished, and the well-polished samples are not demanding on the microscope.
The ultimate goal of metallographic sample preparation is to prepare a flat mirror surface for observation after corrosion or direct observation. The importance of grinding and polishing is obvious. If cutting and inlaying are the preliminary steps of sample preparation, then grinding and polishing is the most important step in the sample preparation process. Friends who are fortunate enough to avoid the cutting and inlaying processes should be more cautious and careful in the grinding and polishing stage, otherwise they will fail.
There are many factors affecting the grinding and polishing process, and the loss of control of each factor will lead to the failure of grinding and polishing. For modern metallographic sample preparation, we must quantify the variables to ensure high-quality grinding and polishing, and all open nodes can be quantitatively controlled. For example, the equipment supports two modes: center loading and single-point loading, disk speed, gripper steering and speed, gripper projection position on the disk, loading pressure, grinding and polishing time, suspension type, filling speed, disk type at each step, etc. If the above links are quantitatively controlled, the accidental factors of successful grinding and polishing will be greatly reduced, and sample preparation will shift from dependence on people to dependence on equipment, lowering the technical entry threshold. After the above links realize equipment control and process control, for samples of specific materials, the main task of the metallographic technician is to find the most optimized parameter combination, and then solidify it and share it with others. This process is destined to be repeated trial and error, and it is inevitable to take a lot of detours. The most labor-saving way is to outsource this work to a professional company. Domestic professional companies such as Shanghai Truer have more than ten years of experience in commissioned sample preparation, accumulated a large amount of sample preparation information, and established a special database, which can quickly obtain the best sample preparation plan.
For high-quality polished samples, taking good photos is a natural thing.
All microscopic analyses are the accumulation and crystallization of countless details, and the same is true for metallographic analysis. Even the most insignificant errors may create obstacles for subsequent observations. Industry practitioners must be in awe and pursue perfection.
