Expert Answers To Questions About Vacuum Technology
With industrial processes becoming more and more advanced as each day passes, there is never a shortage of questions being asked about advanced vacuum technology and PVD coating techniques.
Q: What is meant by the term vacuum coating?
A: This is the technology that is used to coat very thin pieces of work material made from stainless steel. This specific technology is also known as PVD, or Physical Vapor Deposition.
Q: What is considered as the best method of PVD coating?
A: As far as supreme technology, the process known as vacuum ion plating technology is unarguably the fastest that exists today. It is universally regarded in the industry as the most sophisticated method in which to coat surfaces.
Q: Is PVD coating thick?
A: Hardly! The thickness of the typical coating of PVD is actually measured in microns. One micron is equal to one-millionth of a meter.
Q: Is there a particular finish to the surface that is required before administering a PVD coating?
A: No. However, keep in mind that the PVD coating will follow the exact contours of the surface it is applied to. This means that if there are imperfections on the surface, they will still be visible even after the PVD coating has been applied.
Q: How does the process of PVD coating work?
A: In layman’s terms, it goes something like this. The coating goes through a process of either heat evaporation or ion bombardment (known as sputtering). While this is going on, a reactive gas is added to the process. This results in the coating compounding with the metal vapor so that an extremely thin and incredibly adherent coating is place upon the surface of the work material. The thickness is kept at a constant by rotating the parts via several different axes. Due to the high technology of the vacuum that is used, every aspect of the coating process can be controlled down to the most precise level.
These are just some of the most frequently asked questions concerning this very valuable technology that people may be wondering about.
