Have you ever thought about how some of your favorite toys, shiny jewelry from the racks of your local stores, or even the screen of your tablet acquires those pretty colors and protective coatings? It all stems from two pretty cool technologies known as PVD and CVD coating.
PVD (Physical Vapor Deposition) This is a process where materials become vaporized and are then deposited onto a surface to form a thin but strong coat. CVD (Chemical Vapor Deposition) is not that. It works using unique chemical reactions across the gases for a densified layer on a surface.
Factors of PVD & CVD Deposition Based on Vacuum Chamber
So, let’s learn a bit about vacuum chambers and their role in both the given coating technologies, PVD and CVD. A vacuum chamber is a special container that removes air and other gases as part of creating a vacuum that is important for the coating process.
The vacuum chamber in PVD coating should be very clean. This is to prevent dirtiness of the coating material. Due to this, PVD needs very clean vacuum chamber which ensure proper and durable coating.
How Vacuum Chambers for PVD and CVD Processes Compare
CVD coated materials require different environments to be produced within their vacuum chambers. Because CVD relies on chemical reactions between gas, the vacuum chamber must tightly regulate the temperature and pressure to facilitate those reactions.
To be smooth the gases must react in the CVD vacuum chambers. It requires special tools and diligent tracking to achieve optimal outcomes.
Which Needs Better Vacuum Chambers: PVD or CVD
What coating technology requires better vacuum chambers? It just depends on what the project requires. PVD coatings are good in wear resistance and appearance, but CVD coatings stick better and are more even.
PVD processes are more cleanliness-demanding for vacuum chamber usage, but CVD processes rather require higher strictness of temperature and pressure control. Both technologies do well and poorly in some respects and work for different jobs.
Role of Vacuum Chamber Specifications on PVD and CVD Coating Technologies
In summary, the vacuum chamber specifications play a crucial role in either PVD or CVD coating process. The requirements for cleanliness and control of the vacuum chambers for both processes help ensure coatings are of high quality and function.
