Varied Features And Applications Of Tungsten Disulfide

Chemical sciences play an important role in not just the human life, but also in various arenas of the industrial life. Everything around is all about science, the food we eat, the mobile phone we use, the chair we sit on, everything is made of compounds and chemicals. The most common use of compounds and chemicals can be seen in the laboratories.
 

One such compound which is known to be the most lubricious and solid dry lubricant is WS2. It is Tungsten Disulfide that is popular for the dry lubricant property it has. This compound can be used for various applications at high temperature. The compound has the functionality to provide resistance from minus 450 to about 1200 F degree in the normal temperature. The powder of the compound even provides low friction coefficient and hence it is used in numerous applications.
 

Uses of Tungsten Disulfide powder

Though there are numerous applications, but the most basic two uses of WS2 are mentioned below.
 

When the wet lubricants are combined with WS2 powder, the lubricity gets improved. One can use grease, oil or any synthetic as a lubricant. The temperature properties also get improved. The mixture can be used to coat the parts to reduce friction and to enhance the load bearing capacity.
 

The powder made of the Tungsten Disulfide can be coated using sprays. There is no need of any binders for this, and the work can be done at room temperature itself. The coating should be about 0.5 micron in thickness. There is one more method in which the isopropyl alcohol is used. This coating can be used in aerospace parts, engine of the racing car, automotive parts, marine parts, bearings, slitters, valve components, chains, cutting equipment, shafts, mold release, pistons, precision gears, marine parts, knives and slitters, and in many such components.
 

The WS2 can be utilised as the fuel cells in anode and electrolyte anode. It can also be used in the making of nano ceramic parts as it is considered to be good semiconductor. It is even used as effective as well as oil catalysts and made to work in a lot of industrial as well as laboratory applications.
 

Properties of Tungsten Disulfide

This compound comes out naturally and is known to be a rare mineral; it is even called as tungstenite. The compound is used in the procedures of hydrodenitrification and hydrodesulfurization. The nanoparticles of Tungsten Disulfide offer great performance in the lubricating material. In addition to this, they can be used in high pressure, load, vacuum, and in high temperature as well. The compound has friction coefficient property that can be used in metals as additives in order to result in stable friction.
 

Moving on, there is good oxidation resistance in Tungsten Disulfide which can be utilised in improving the ability of grease and oil and improves antiwear and pressure functionalities. The nanoscale particles of WS2 can be added in casting process which will give absorption and lubricating properties on metals.
