A friend posted a consultation on Baidu; How to use aluminum oxide polishing solution for polishing;, The specific content is to inquire about the plan to use alumina polishing solution for precision polishing, starting with 0.3 μ M, followed by 0.05 μ M's alumina polishing solution. But it is unclear how long it will take to polish, how much N of loading force will be used, and whether water needs to be added.


After reading this post, the metallographic editor of Lianneng realized that the novice still has some confusion about how to use alumina polishing solution for polishing. In fact, it's not a problem to properly use aluminum oxide polishing fluid to throw out the ideal surface! Today, the metallographic editor of Chain Energy will review the usage methods of conventional materials for aluminum oxide polishing solution for your reference.

    The particle size range of alumina polishing solution is generally 0.05 μ m. 0.3 μ M and 1 μ Several particle size models are mainly used for final polishing of metallographic samples. Effectively remove scratches and perfectly reproduce the microstructure morphology. Suitable for most materials, but there are slight differences in usage methods depending on the type of material.

    The above is a reference method for using alumina polishing solution for final polishing of commonly used materials. It should be mentioned whether water needs to be added during the polishing process. It is necessary to add lubricating fluid (note: special polishing cooling lubricating fluid) or water when fast polishing with a speed of 500 or more. When adding lubricating fluid or water, be careful not to flow too fast, otherwise it is easy to wash away alumina particles.


Also, for metal materials that are prone to oxidation, polishing with water can easily oxidize, and alcohol can be used as a cooling lubricant. No matter which type of cooling lubricant is used, just ensure that the polishing cloth is moist, and then the impurities cut off from the polishing cloth do not accumulate on the polishing cloth.


It should also be noted that during grinding and polishing, whether it is aluminum oxide polishing solution, diamond polishing solution, or polishing paste or other polishing agents, try to spray or apply them to the center of the rotary table as much as possible to ensure that the polishing agent is lost as little as possible and effectively grind and polish the surface of the sample.


The above is a brief explanation of the usage method of aluminum oxide polishing fluid. Properly using aluminum oxide polishing fluid to polish and throw out a perfect surface is really not a problem! I hope I can help my friends.
