Comet tails occur adjacent to inclusions or pores, when the motion between sample and polishing disk is unidirectional. Their characteristic shape earns the name "comet tails." A key factor in avoiding comet tails is the polishing dynamics. 1. During polishing, use the same rotational speed for the samples and the disk. 2. Decrease the force. 3.
