Advantages and disadvantages of molybdenum disulfide coatings

Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and pressure. It is also diamagnetic, can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductivity, and has the functions of rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for dehydrogenation of complex hydrocarbons.

Molybdenum disulfide coating Anti-corrosion self-lubricating coating contains ultra-fine molybdenum disulfide (MoS2), gray-black, room temperature curing type antifriction coating lubricant. Good abrasion resistance, extreme pressure resistance, and self-lubricating performance. Dry film lubrication, dust and pollution prevention. Simple and easy to apply, durable and effective. Environmental requirements are relatively low. Molybdenum disulfide is a coating designed for the coating of large workpieces with outdoor requirements for corrosion resistance and wear resistance. It is especially suitable for anti-friction lubrication between normal temperature environment and slow sliding surface of parts with large contact surface.

Antioxidation: Molybdenum disulfide is obtained through chemical purification and comprehensive reaction. Its PH value is 7-8, which is slightly alkaline. It covers the surface of the friction material, can protect other materials, prevent them from being oxidized, especially makes other materials difficult to fall off, and enhances the adhesion.

Anti-friction: The particle size of molybdenum disulfide obtained by supersonic jet milling can reach 325-2500 mesh, micro-particle hardness is 1-1.5, and friction coefficient is 0.05-0.1, so it can be used to reduce friction in friction materials.

Molybdenum disulfide also has its shortcomings, such as poor thermal conductivity, low enough friction coefficient, and not strong permeability (compared to thin oil). These shortcomings are the main obstacles to further expanding the scope of use.

In contrast to the industrially developed regions, the research on solid lubricants is very important, and international lubrication conferences have been specifically held to exchange information and discuss new process technologies. Frictions have been established in some industrially developed regions in the United States, Japan, and Western Europe in recent years , Wear and lubrication center.
