 · After a metallographic sample has been mounted, grinding and polishing creates a flat and even surface. Any potential residue from the mounting process or damage from the sectioning process are ground off to expose the actual microstructure of the sample. Polishing removes abrasions from the previous steps to provide a smooth surface.

3. Electrolytic mechanical compound grinding: A conductive abrasive tool is used to apply electrolyte and voltage between the abrasive tool and the grinding surface. Under the combined action of mechanical and electrochemical polishing, the surface roughness is reduced and the surface gloss is improved.

POLISHING. Polishing is the most important step in preparing a specimen for microstructural analysis. It is the step which is required to completely eliminate previous damage. Ideally the amount of damage produced during cutting and grinding was minimized through proper blade and abrasive grinding so that polishing can be minimized.

1. Mechanical grinding: Titanium has high chemical reactivity, low thermal conductivity, high viscosity, low mechanical grinding and grinding ratio, and is easy to react with abrasives. Ordinary abrasives are not suitable for titanium grinding and polishing. Hard abrasives, such as diamond, cubic boron nitride, etc., the polishing linear speed is generally 900 ~ …

 · Polishing is considered multidirectional, which means that the final surface scratches, albeit invisible, are oriented in many directions. Some examples of ground and polished surfaces are shown in Figure 16-6. Note that the differences in surface appearance are subtle because of the transitional nature of the grinding and polishing processes.
