FORMATION AND PROPERTIES OF LANGMUIR–BLODGETT FILMS OF 2,4-HENEICOSANEDIONE WITH BORON NITRIDE PARTICLES
Abstract
Tribological properties of composite Langmuir–Blodgett monolayers of 2,4-heneicosanedione (HD) with particles of hexagonal (α-BN) boron nitride formed on silicon and steel surfaces by the horizontal precipitation method have been studied.
It was found that incorporation of α-BN (the average particles size ~ 600 nm) into the structure of the HD Langmuir layer resulted in an increase of minimal area per molecule from 0.27 to 0.34 nm2 and wear stability of HD monolayer. Composite LB films of HD with α-BN particles can be used as protective coatings in precision friction units.
