Characterization of Protection of SAE 10W-30 Lubricant Wear Protection with the addition of MOS2 additive nano as a modification of friction

Introduction

The use of lubricants in engines is crucial to reduce wear and tear, increase efficiency, and prolong the lifespan of the engine. SAE 10W-30 lubricant is a widely used lubricant in various engines due to its excellent lubricating properties. However, the wear protection of this lubricant can be improved by adding nano additives, such as MOS2. This study aims to investigate the effect of adding MOS2 nano additives to SAE 10W-30 lubricant on its wear protection and friction reduction.

Background

Lubricants play a vital role in reducing friction and wear between moving parts in engines. The addition of nano additives to lubricants has been shown to improve their wear protection and friction reduction properties. MOS2 is a type of nano additive that has been shown to have excellent solid lubrication properties, which can help reduce wear and friction in engines.

Methodology

This study used Sodium Dodesil Sulfate (SDS) surfactants to prevent the deposition or clumping of Nano MOS2 particles when the engine is cold. The optimal composition of Nano additives MOS2 was found at a concentration of 0.1% and SDS 0.2%% (WT%), which was produced from composition variations in 12 different samples. Testing was carried out using two instruments, namely testing the diameter of the disc (fourball scar diameter) and HFRR (High-Frequency Reciprocating Rig) testing.

Results

The results of the test diameter of the disc showed that without nano additives, the diameter of the former disc was 0.31 mm, while with nano additives, the diameter of the former disc decreased to 0.26 mm. This showed an increase of 16% in the protection of the former disc. HFRR testing on wear and wear showed significant results. Without nano additives, the value of the wear of wear was 167.5 μm, while with nano additives, the value of former wear dropped to 96 μm, or a decrease of 42.7%. This indicated that the addition of MOS2 additives effectively reduced wear and wear on the friction surface.

Additional Analysis and Explanation

The addition of Nano additives MOS2 to the SAE 10W-30 lubricant has a significant positive impact in increasing wear resistance and reducing friction. This can be explained through several mechanisms:

Formation of a protective layer

Nano MOS2 particles form a thin and strong layer on the friction surface, which functions as a barrier between the metal surface and prevent direct contact. This layer reduces friction and wear by minimizing metal-to-metal contact.

Solid lubrication properties

MOS2 has a good solid lubrication properties, which allows lubricants to work more effectively in extreme conditions, such as high temperatures and heavy loads.

Increased viscosity

Nano additives MOS2 can increase the viscosity of the lubricant, which helps reduce wear and friction by increasing the thickness of the lubricating film.

Conclusion

This study proves that the addition of Nano additives MOS2 can increase wear resistance and reduce friction in the SAE 10W-30 lubricant. The use of nano additives can provide significant benefits in improving the performance and age of the engine, especially under extreme operational conditions.

Future Work

Future studies can focus on investigating the effect of different concentrations of MOS2 nano additives on the wear protection and friction reduction properties of SAE 10W-30 lubricant. Additionally, the study can be extended to investigate the effect of MOS2 nano additives on other types of lubricants.
