Oleylamine-modified NiFe-LDH/MoS₂ Nanocomposite Lubricant Additive

36% lower COF under heavy load

Combines the high adsorption capacity of rigid LDH with the low-shear property of flexible MoS₂ to form a robust tribofilm, greatly improving anti-wear and friction-reduction under extreme conditions.

Advantages

Fast film formation

The abundant adsorption sites provided by rigid NiFe-LDH lamellae enable rapid anchoring of the nanocomposite on metal surfaces, synergistically forming a protective film with MoS₂.

Anti-wear at 150°C

Exceptional anti-wear performance is maintained at 150°C in steel-steel contacts, significantly outperforming neat PAO6 and OA-MoS₂ alone, indicating sufficient thermal stability for high-temperature operation.

36% lower friction

At 75°C and 392 N, the coefficient of friction decreases to 0.066, a 36% reduction compared to base oil, leading to lower energy consumption and wear.

Applications

• Industrial gear and bearing lubrication：Quickly forms a transfer film in heavy-load gears and bearings to reduce friction and wear, extending maintenance intervals.
• Aero-engine lubrication：Maintains lubrication under high temperature and load to meet aero-engine demands, reducing failures from lubrication breakdown.
• Heavy-duty machinery lubrication：Suitable for heavy-duty machinery by forming a durable tribofilm that protects metal surfaces, significantly reducing wear and energy consumption.
