Molybdenum Disulfide Coatings (MoS2 coatings), also known as Moly Coatings are commonly used in applications where load carrying capacity, operating pressure and coefficient of friction are primary concerns. This coating provides effective lubrication in a wide range of loads, in many cases exceeding 250,000 psi.
Introduction Researchers realized the potential and the impor- tance of molybdenum disilicide as early as 1949, as is evident from the rich body of literature of the time dealing with the synthesis, processing and charac- terization of this material [1, 2].

Molybdenum disilicide (MoSi 2, or molybdenum silicide), an intermetallic compound, a silicide of molybdenum, is a refractory ceramic with primary use in heating elements.It has moderate density, melting point 2030 °C, and is electrically conductive.
Molybdenum disulfide is a solid film lubricant, which can be used in the manufacturing of different types of industrial products. These include gear oils, pastes, paint like coatings and other grease based lubricants. Also known as MoS2, the lubricant can perform in applications with wide temperature ranges and pressures, while maintaining its basic structure. For these reasons, MoS2 is often .

Molybdenum Heating Elements. H.C. Starck’s molybdenum is a superior, pure and alloyed refractory material for heat treating medical, aerospace, defense and automotive products in high temperature furnaces that include medical devices, aircraft and aerospace components, nuclear fuel pellet production, and high pulse magnet research applications.
Molybdenum disilicide (MoSi2) is a promising candidate material for high temperature structural applications. It is a high melting point (2030 °C) material with excellent oxidation resistance and a moderate density (6.24 g/cm3). However, low toughness at low temperatures and high creep rates at elevated temperatures have hindered its commercialization in structural applications. Much effort .
Processing of MoSi 2 via a lower‐temperature reactive vapor infiltration route is explored. In this process a loosely compacted molybdenum powder is exposed to a gaseous silicon precursor. Initially, a surface MoSi 2 layer forms and, as the process proceeds, a distinct reaction front moves progressively inward. At 1200°C, the silicide layer .

Find suppliers and manufacturers of Elements and Molybdenum Disilicide for nearly any high-temperature thermal processing equipment system, component, and/or supplies.
However, these applications can be strongly restricted due to (1) processing difficulties and (2) low fracture toughness. In this work, to address these two difficulties we have used two additives, which are multi-walled carbon nanotubes (CNTs) and molybdenum disilicide (MoSi2).
However, it is known that molybdenum disilicide shows a good oxidation resistance in the temperature range up to 1650 °C. Therefore, the aim of this work is the application of molybdenum disilicide coatings for high-temperature oxidation protection of molybdenum-based substrates.

Molybdenum disilicide (MoSi 2) is a candidate material for high temperature structural applications due to its high melting point and excellent oxidation resistance.A major impediment to implementing this material is its low temperature fracture toughness.
Molybdenum disilicide composite tubes have been produced by the Exotherm Corporation using a low cost combustion synthesis process. Los Alamos National Laboratory was granted two patents in 2001 regarding methods used to produce molybdenum disilicide composites (#6,197,247 and #6,300,265). This project concluded in 2001. • • • • • •

Molybdenum disilicide elements are manufactured in several grades of elements, with the primary difference being the MET in a certain atmosphere. The METs in non-air atmospheres and vacuum are significantly higher than those for metallic or SiC elements due to the stability and regeneration characteristics of the protective layer that forms on .
The authors investigate the synthesis directly in coatings of a borosilicate melt that could fill the role of glassy matrix, thereby avoiding fusion and processing of the glassy material. The effect of added boron on the formation of coatings based on molybdenum disilicide and tungsten disilicide in air at 900 degrees C is presented.
Inspection of the scientific literature reveals that intermetallic compounds have, in recent years, attracted considerable interest as a result of their unique elevated temperature characteristics. Among the wide range of intermetallic compounds that are actively being studied, MoSi2 has been singled out as a result of its unique combination of properties, which include an excellent oxidation .
