Magnetron Sputtering of CoFe and Permalloy
You are watching the sputtering of CoFe and Permalloy on a 3 inch Si wafer. The first faint plasma is the CoFe sputtering. When the CoFe gun shuts off the screen goes dark and the Permalloy gun is turned on. The plasma from the Permalloy deposition follows the path of ...

In magnetron sputtering with a suitable magnetic field configuration it is also possible to control the microstructure, chemical and phase composition of the growing film. Besides balanced discharges, two types of unbalancements are possible: type I and type II.
In type I, the plasma that is not strongly confined on the ...

As this website concentrates on magnetron sputtering the history of PVD coatings concentrates on magnetron sputtering. The history of other deposition methods such as arc evaporation will be added at a later date.
Origin of the term Physical Vapour Deposition, PVD
The term physical vapour deposition, PVD seems to have been ...

Continue Reading...PVD coatings for tooling In the areas of machining and tooling PVD coatings deposited using vacuum coating machines are widely used to increase the life and productivity of production tools saving companies billions of dollars worldwide. The use of PVD coatings saves companies money in three ways. Firstly PVD coated tools can be run faster reducing cycle times and enabling the production of more components in less time. Secondly PVD coatings reduce wear and pickup reducing downtime due to tool replacement. Finally PVD coatings reduce the need for cutting fluid. Cutting fluids cost companies today up to 15% of their total production costs. PVD coatings can be run dry or with very limited amount of fluid.
PVD coatings for components In the area of machine components large vacuum coating machines are used to deposit low friction PVD coatings that reduce energy losses and the need for lubricant. Hard (2000 VHN), wear resistant, low friction coatings can be deposited with a friction coefficient <1/2 that possible using oil lubrication therefore eliminating the need for lubricant. These coatings are used extensively in motor sport. Decorative PVD coatings are also widespread as all colours can be deposited.
More information about PVD coating applications PVD coatings are used in many industrial applications, for more information about PVD coating applications click the link or use the menu at the top of the page.
Your guide to PVD coatings This website provides a guide to PVD coating theory, PVD coating applications and PVD coating technology. Just click the links or use the dropdown menu to find out everything you need to know about PVD coatings. The PVD coatings sitemap is also useful.
The majority of the PVD coating information in this website concentrates on magnetron sputtering as this technology is the most versatile and is consequently the most suitable for a greater range of applications. However cathodic arc evaporation and pulsed laser ablation are used in some applications and therefore the basics of these two vacuum deposition techniques are given.
