(The effect of Manganese in carbon steel.)
Purpose.
The effect of Manganese in carbon steel.
Theory.
Polishing.
Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with significant specular reflection and minimal diffuse reflection. When the surface is magnified thousands of times, it usually looks like mountains and valleys. By repeated abrasion, those `mountains` are worn down until they are flat or just small `hills.` The process of polishing with abrasives starts with coarse ones and graduates to fine ones.
Corrosion.
Corrosion can be defined as the disintegration of a material into its constituent atoms due to chemical reactions with its surroundings. In the most common use of the word, this means a loss of electrons of metals reacting with water and oxygen. Weakening of iron due to oxidation of the iron atoms is a well-known example of electrochemi¡¦(»ý·«)
