Karakterisasi Sifat Perlindungan Keausan Pelumas SAE 10W-30 dengan Penambahan Nano Aditif MoS2 sebagai Pemodifikasi Gesekan.

Abstract

Had been done research of characterization wear protection of lubricating oil SAE 10W-30 with nanoparticle additive Molybdenum disulfide (MoS2) as friction modifier. The research used surfactant sodium dodesil sulfate (SDS) to prevent sedimentation or agglomeration nanoparticle MoS2 when the engine is cold. The most optimal composition of nano additive MoS2 0.1%weight andSDS 0.2 %weight (wt%), obtained with varying the samples with 12 diffrent samples composition. The test used with 2 instruments test, fourball scar diameter and HFRR(High-Frequency Reciprocating Rig). The results of Fourball scar diameter test: without nano additive 0.31 mm and with nano additives 0.26 mm, or 16% increase protection scar diameter. The results of HFRR(High-Frequency Reciprocating Rig) wear scar test: without nano additive 167.5 μm and with nano additives 96 μm, or 42.7% reduce the value of wear scar. The results of HFRR friction test: without nano additive 0.124 andwith nano additives MoS20.122, or 1.61% reduce the value of friction.
