Abstract

The morphology and tribological properties of Langmuir–Blodgett mono- and bilayers of stearic acid with particles of molybdenum disulfide (MoS2) and amorphous carbon (С), prepared on silicon and steel substrates by horizontal deposition (stearic acid–MoS2 and stearic acid–С monolayers) and by the “roll” technique (stearic acid–MoS2/stearic acid–С bilayers), were studied. Incorporation of C and MoS2 particles into the structure of a stearic acid film enhances its wear resistance by a factor of 2.8 and 5.5, respectively. The presence of MoS2 and С particles and of their aggregates of size from ~220 nm to 16.3 μm in stearic acid layers was confirmed by atomic force microscopy.
