Tungsten disulphide or WS2 as it is called; is a synthetic powder that is often converted into and used as a lubricant. Various elements present in the powder such as hexagonal crystal clusters and lamellar lattice structure create a certain amount of friction. This makes tungsten disulphide a very lubricious material, and thus a perfect solution when it comes to applying protective coatings on various products.

This makes tungsten disulphide a very lubricious material, and thus a perfect solution when it comes to applying protective coatings on various products.

There are many types of processes used to apply a coating of tungsten disulphide:

  • Spray Blasting
  • Buffing
  • Tumbling or bowl coating
  • Adding Ws2 to a lubricating media

The most tried and acceptable method in industries worldwide is that of spray blasting. The spray blasting method comprises:

Before Spray Blasting:

  • Enclose the coating area with plastic sheets. This helps to keep the spray dust from spreading outside the work area.
  • Keep aside cloths or tissues that will be used during the coating process.
  • Have necessary oils or sprays to clean and degrease the part that is going to be sprayed.

Spray Blasting Method:

  • Clean the required and remove any traces of grease from it. The less amounts of other substances on the part, the easier it will be to apply the coating.
  • First, the part needs to be sand blasted. Use 5 micron Alumina powder during this part of the method. A light spray will do.
  • Once the powder has settled, clean the part thoroughly, removing any traces of the Alumina powder.
  • Using cold pneumatic air, sand blast the part with the WS2 powder. Spray-coat the part till its color changes to silver grey.
  • Using a cloth or a tissue, wipe off any extra traces of the powder.

WS2 is perfect for a variety of applications including:

  • Race car engines
  • Power transmission components
  • Piston cylinders
  • Aerospace components
  • Machinery Components
  • Automotive parts
  • Spindles

These are only a few applications for the part. As one can see, tungsten disulphid coating  can be used by many industries. For best results, contact Microsurface Corporation in San Jose, CA for professional application.
