In metallographic sample preparation, polishing cloth is an indispensable part of the polishing process. It not only carries and secures the polishing abrasive but also utilizes its unique fiber structure to finely cut and flatten the sample surface, making it key to achieving a bright, scratch-free observation surface.

Induction hardening is a heat treatment process that locally or entirely hardens the surface of metal workpieces through the principle of electromagnetic induction. This process features fast heating speed, minimal deformation, low energy consumption, and strong controllability, and is widely used for surface strengthening of components such as gears, shafts, and guide rails.

Can you just mount your sample after cutting it? Not necessarily! Have you ever, or are you still, skipping pre-treatment steps? You know, proper pre-mounting preparation directly determines the success or failure of subsequent polishing, observation, and even electron microscopy analysis—especially for complex samples. A little carelessness can affect imaging at best, or even mislead conclusions at worst. Today, we'll systematically review the essential pre-mounting considerations.
