Molybdenum disulphide or MoS2 is an inorganic compound which is extensively used in industries as a dry film lubricant and friction minimizing coating. One of the significant characteristics of this coating is its extensive corrosion resistance capacity against most of the corrosive agents like high temperature, moisture, friction or even harsh chemicals used quite normally in various industrial purposes. This is the basic reason why molybdenum disulphide coating is applied as a solid or dry lubricant on equipments, machines, motors, pumps, belts etc. This is also referred to as Moly Coatings, and they are actually meant to be used on specific equipments and machines where the primary concern is to safeguard the applications from high friction rate, abrasion from carrying heavy loads and extreme temperatures.
- These coating offers an extensive range of protection through lubrication for a wide spectrum loads used in industrial sector up to 250,000 psi.
- In order to avail optimum quality, you need to blend the molybdenum disulphide coating with resins, binders or water-soluble sulfides. In this combined form it offers the maximum lubricating as well as corrosion resistance.
- Basically, the Molybdenum disulphide is a naturally mined compound which is found in black solid form almost similar to graphite. Owing to its particular geothermal origin it is induced with the inherent characteristic quality of high resistance against corrosion, temperature, friction as well as the ability to withstand pressure.
- Moreover, even under the influence of oxygen or dilute acid, it offers no change in composition and protects the machines and applications coated with it.
Owing to its unique characteristic features and corrosion management qualities it is distinguished from other dry or solid lubricants. This lubricant off late has become very popular in the business industry. It has the exclusive ability to offer adequate lubrication in industries to machines and applications exceeding 250,000 psi. Not only this, it also showcased a relatively low coefficient rate of friction. Again, unlike any other dry or solid lubricant it exhibits the ability to withstand and resist temperatures as high as 350°C under oxidizing conditions. MoS2 is also known to resist reaction with other solvents and remain unchanged in the presence of other solvents. Under non-oxidizing environments it can resist up to 1100°C. Molybdenum disulfide coatings are generally thermally cured especially for industrial purpose. When applied on a base it is bonded with that metal. Apart from this specific type of use in industries, it also finds abundant requirement in grease bonding for bearings, chassis, splines or even paste form as well for a wide range of other industrial use.
Importance of Molybdenum disulphide coating
Corrosion stands to be a major problem in industries where machineries, equipments, motors, pumps, belts etc are used on a daily basis. These are certain elements that are prone to corrosion. The climatic conditions in each area are different and we all know that humidity, and high temperature can corrode the industrial equipments quite easily. This is a coating which stays put even at high temperatures. Industries can actually save 25% to 30% of their budget spent to deal with corrosion issues by applying molybdenum disulphide coating. By minimizing the risk of corrosion, you can also control the amount of accidental risks, machine malfunctioning, delay in production due to corrosion related issues with the equipments and the time spent for repairs, repair costing etc. Therefore, it is basically a protective measure and this molybdenum disulphide coating plays a vital role in industries and for corrosion management. Therefore, you can consider the use of molybdenum disulphide for coating as well to save on extra expenditure due to corrosion.
