Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!
Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low
Another case is that the chemicals in the polishing fluid react with the Co phase in the alloy, causing the Co to overflow or Co to deposit again, so that you need to consider whether you need to replace the polishing fluid.
First of all, is the alloy itself if there are problems, product patterns, mainly to see the pattern is a kind of form, if a cluster or cluster, is generally the product of carburizing, such products also have a feature in 40 times under the anatomical microscope observation, can see the concave point, the because the graphite particles in the grinding conditions, free C from the alloy caused by the desquamation of this kind of products, should not be a problem after carburizing burnback.
