The visibility of the boundary between WC particles and cobalt bonding phase during grinding and polishing of sintered carbide samples depends on the surface of the metallographic polishing cloth used in the subsequent preparation steps of the sample. If you don't pay attention to the boundaries, but rather want to easily observe graphite or η Similarly, it is necessary to use a lint free polishing cloth, such as a medium polishing cloth or a coarse polishing cloth imported from the United States.
