Overview of Few Layers Tungsten Disulfide Nanopowder Nano WS2 Powder For Lubricant
Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.
When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.
Feature of Few Layers Tungsten Disulfide Nanopowder Nano WS2 Powder For Lubricant
The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Parameters of Few Layers Tungsten Disulfide Nanopowder Nano WS2 Powder For Lubricant
Tungsten disulfide (WS2) nanoparticles, also known as nano WS2 powder, have unique properties that make them suitable for various applications, including lubricants due to their exceptional lubricity, thermal stability, and anti-wear characteristics. Here are some key parameters for using few-layer tungsten disulfide nanoparticles in lubricants:
1. Particle Size: Few-layer WS2 typically has sizes ranging from 1 to 10 nanometers, providing a large surface area to volume ratio, which enhances its lubricating performance.
2. Surface Area: High surface area allows for better dispersion in the lubricant, facilitating film formation and reducing friction between moving parts.
3. Thermal Stability: WS2 has a high melting point (approximately 1600°C), making it resistant to elevated temperatures, which is crucial for maintaining lubrication under harsh conditions.
4. Low Coefficient of Friction (COF): Nano WS2 reduces friction significantly, improving energy efficiency and extending component life.
5. Anti-Wear Properties: The layered structure of WS2 acts as a self-lubricating layer, protecting metal surfaces from wear and tear.
6. Chemical Stability: WS2 is chemically inert, which means it can resist degradation under various chemical environments, ensuring long-term lubrication performance.
7. Dispersion: WS2 particles need to be well-dispersed in the lubricant matrix for effective action. Suitable surfactants and processing techniques are essential to achieve proper dispersion.
8. Viscosity: The addition of WS2 nanoparticles can influence the viscosity of the lubricant. Depending on the application, it may require adjusting the base oil viscosity to maintain optimal performance.
9. Compatibility: It’s important to ensure compatibility between WS2 and the base lubricant to avoid phase separation or detrimental reactions.
10. Environmental Impact: WS2 is considered a greener alternative to traditional lubricants due to its non-toxic nature and low environmental impact.
To optimize the performance of few-layer WS2 in lubricants, thorough research and experimentation are required to determine the appropriate concentration, processing methods, and formulation for a specific application.
