What Are Excellent Properties of Molybdenum Disulfide in High Temperature Grease? 271

Molybdenum disulfide (MoS2) is a naturally occurring black solid compound that is slippery to the touch. It transfers easily and adheres to other solid surfaces it comes in contact with. Its mineral form — called molybdenite — was often confused with graphite until the late 1700s. Both have been used for lubricating and writing materials for centuries. So, what are the excellent properties of MoS2 in high temperature grease? 1)it can improve the bearing capacity of the grease and make…

Advantages of Molybdenum Disulfide Coating Based on MoS2 308

Molybdenum is a lustrous silver metal found in the earth’s crust at 1.5 ppm. In many cases, it is very similar to tungsten, which is often paired with tungsten in the transition series of the periodic table, but their chemistry often exhibits more pronounced differences than expected. The metal can withstand extremely high temperatures without significantly changing, expanding or softening. This ability makes its engagement in high temperature situations very useful. Typical applications of molybdenum are various, such as crucibles,…
