Physical vapor deposition is a method that places thin films or coatings on surfaces by solidifying the material in a high vacuum. In doing so, it ensures that no chemical reactions that could compromise the work being done are triggered at the time of working.

PVD: Increasing productivity with graphite suspensions

What is PVD?

PVD, or physical vapor deposition, is a method that places thin films or coatings on surfaces, through the solidification of the material in a high vacuum. With this, it achieves that at the moment of working, no chemical reactions are provoked that could compromise the work being done.

The metallization on the surface is used so that the machine can resist all types of corrosion or erosion. It also allows the machine to work at high temperatures. With its lubricating properties, it interposes itself to the friction between the parts, stopping their wear.

The physicl vapor deposition is used in PVD for:

  • Create solar cells
  • Packaging foils (such as chip bags)
  • Creating cell phone or electronic equipment parts
  • Cell phone cases are made with this process to avoid static.
  • Working with metal, either by melting it or molding it at high temperatures.
  • Used in scientific accessories such as microscopes.
  • Used in the process of creating polypropylene foil.
  • Different types of chrome plating can be done using PDV
  • The processes used are clean and environmentally friendly, as it avoids extra waste.

What is a graphite suspension?

Graphite suspensions and coating improve PVD productivity, by protecting the chambers wall with a thin graphite coating that acts as a release agent for metal deposition on the chamber walls and other components.

Therefore, graphite suspension is vital for this process and ESGRAF has suspensions developed as demolding agents and resist high temperatures, always with the best quality and focusing on your needs.

Conclusions

Graphite coatings increase PVD productivity and protect the process chambers from incrustation of metal coatings,so that it is easy to clean any residue and avoid corrosion and plaque.

Limitations to consider

Performance depends on graphite grade, grain orientation, temperature, load, pressure, speed, and operating environment. Material selection should be confirmed for your actual process conditions.

Information needed for a quote

To guide selection or prepare a quote, ESGRAF typically needs:

  • Application and operating conditions (temperature, atmosphere, load).
  • Dimensions, technical drawing, or CAD file when applicable.
  • Required quantity.
  • Requested grade or material currently in use.
  • Observed issue with the previous part or lubricant, if any.

Spheroidal graphite cast iron - in which industries is it needed?

Cast irons are a group of ferrous alloys that have a large number of properties and have above 2% carbon. In these cases the carbon does not dissolve completely in the iron and solidifies in the form of graphite or iron carbide. One of the types is spheroidal graphite cast iron or nodular cast iron.
