Working principle of plasma polishing

Plasma, also known as the fourth state of matter, is an electromagnetic gaseous discharge phenomenon, which partially ionizes gaseous particles. The ionized gas includes atoms, molecules, atomic clusters, ions and electrons. Plasma is in high temperature and high pressure, the polishing agent is water-soluble, the electron will leave the nucleus and run out, the nucleus will form a positively charged ion, when these ions reach a certain number can become plasma state, plasma state energy is very large, when these plasma and the object to be polished friction, instantly will make the object to achieve the surface bright effect. Plasma polishing is a new metal surface treatment process. Only the molecular layer on the surface of the workpiece reacts with plasma. The atomic spacing in the molecule is generally 0.1-0.3 nm, and the treatment depth is 0.3-4.5 nm. The surface roughness of the polishing material is within 1 mm, so plasma chemistry can activate the surface of the workpiece, remove the surface molecular pollution layer, and cross link the surface chemicals.

Advantages of plasma polishing

Polishing technology is one of the key technologies of metal surface treatment. Polishing is an indispensable production step in both traditional and digital industries. Polishing is the process of finishing the surface of the workpiece. After polishing, the surface roughness of the workpiece is reduced. Generally speaking, with the improvement of glossiness, the mechanical, physical and chemical properties of the workpiece are improved to varying degrees. For example, the roughness is reduced, the finish is improved, the corrosion resistance is improved, the notch sensitivity is reduced, the friction coefficient is reduced, and the wear is reduced.

Plasma polishing is a new polishing technology which is completely different from the traditional methods. This polishing technology is developed and designed according to the principles of electrochemistry and chemical reaction. Its polishing technology does not use chemicals that pollute the environment and damage the health of producers, but its polishing effect can reach the high quality that is difficult to achieve by traditional methods, and the polishing speed is beyond the traditional polishing methods, and the production cost is far lower than the traditional polishing cost
