Overview of Nano-MoS2 90nm Molybdenum disulfide flakes For High Temperature Lubricant
Molybdenum (Mo) is a chemical element with the atomic number 42 and is represented by the symbol Mo on the periodic table. It is a transition metal located in group 6 and period 5. Molybdenum is known for its high melting point, excellent strength, and thermal stability, making it a crucial component in various industrial applications.
Feature of Nano-MoS2 90nm Molybdenum disulfide flakes For High Temperature Lubricant
-
High Melting Point: Molybdenum has one of the highest melting points among all pure elements, at 2,623°C (4,753°F). This property makes it ideal for high-temperature applications.
-
Strength and Toughness: Even at high temperatures, molybdenum maintains its strength and hardness, which is essential for use in extreme environments.
-
Corrosion Resistance: Molybdenum exhibits good corrosion resistance to many acids and alkalis, although it can be attacked by oxidizing acids like nitric acid.
-
Thermal Conductivity: It is an excellent conductor of heat, making it suitable for applications where efficient heat transfer is required.
-
Alloying Agent: Molybdenum is widely used as an alloying agent, particularly with steel, to enhance hardness, toughness, and resistance to wear and corrosion. Stainless steels often contain molybdenum for these properties.
-
Electrical Applications: Due to its low resistivity and high-temperature stability, molybdenum is used in electrical contacts and heating elements.
-
Lubricity: Molybdenum disulfide (MoS₂) is a common dry lubricant, providing low friction surfaces in high-pressure, high-temperature conditions.

Parameters of Nano-MoS2 90nm Molybdenum disulfide flakes For High Temperature Lubricant
Nanoscale MoS2 flakes have shown promise as high temperature lubricants due to their excellent thermal stability and high melting point, making them suitable for use in extreme heat environments. The fabrication of these flakes involves the reduction of MoS2 monolayer films on a support material using chemical reduction techniques.
To determine the parameters of high temperature lubricants made from MoS2 flakes, you would need to perform experiments that measure various properties such as molecular weight, density, viscosity, and wear resistance. Some of the specific parameters that may be relevant include:
1. Molecular weight: The molecular weight of a lubricant is an important parameter as it determines its molecular weight distribution and fluidity at different temperatures. Low molecular weight lubricants tend to be more compressible and flow smoothly at higher temperatures compared to high molecular weight lubricants.
2. Density: The density of a lubricant can affect itsViscoelastic behavior and its ability to absorb and transfer heat. Higher densities generally lead to lower frictional forces and better thermal stability.
3. Viscosity: Viscosity is another critical parameter for determining the effectiveness of high temperature lubricants. Different materials have different viscosities at different temperatures, and selecting a lubricant with the right viscosity can improve its performance in extreme environments.
4. Wear resistance: Wear resistance is a measure of how well a lubricant resists the wear caused by friction between moving parts. High wear resistance can reduce maintenance costs and extend the life of machinery.
Overall, optimizing the parameters of high temperature lubricants made from MoS2 flakes requires careful consideration of factors such as molecular weight, density, viscosity, and wear resistance. Experimental studies using ing tools like rheology meters and surface hardness testers can provide valuable insights into these parameters and help design more effective lubricants for high temperature applications.
