Nanoparticles Show Promise in Improving Wear Resistance of Wind Turbine Gears

Researchers from Beijing Jiaotong University have discovered a novel way to improve the wear resistance of wind turbine gears by using a new lubricant additive made from magnesium silicate hydroxide (MSH) and titanium dioxide (TiO2) nanoparticles. The additive, called MSH/TiO2, was prepared using spray drying technology and has shown significant improvements in friction coefficient and wear rate reduction compared to traditional lubricant additives.

Key Takeaways:

• The MSH/TiO2 composite microspheres have an average particle size of 2.43 ± 1.23 μm and a smoother and denser surface compared to traditional MSH lubricant additives.
• The MSH/TiO2 microspheres have a lower average friction coefficient and a wear rate reduction of 63.5% compared to traditional lubricant additives.
• The tribological properties of MSH/TiO2 are attributed to the formation of a mixed tribofilm with a synergistic strengthening effect on the worn surface.
• TiO2 nanoparticles dispersed on the mixed tribofilm improve its hardness and bearing capacity, and increase the ability of the worn surface to resist plastic deformation and abrasive wear.
• The research was funded by the Fundamental Research Funds for the Central Universities and the Tribology Science Fund of State Key Laboratory of Tribology.

Statistics:

• 63.5% reduction in wear rate of MSH/TiO2 microspheres compared to traditional lubricant additives.
• 2.43 ± 1.23 μm average particle size of MSH/TiO2 composite microspheres.
