Lubricants
consist of base oils and chemical additives such as dispersants, surfactants,
oxidation inhibitors, and antiwear agents. Organic and inorganic boron-based
additives increase wear resistance and decreases friction. Hexagonal boron
nitride and metal borates are used for this purpose. Zinc borate is a synthetic
hydrated metal borate. The production techniques of zinc borate generally
include the reaction between zinc source materials (zinc oxide, zinc salts,
zinc hydroxide) and the boron source materials (boric acid and borax).
The nano zinc borate
particles were prepared from zinc nitrate and borax in the present study by
using low initial zinc and borate concentrations and low temperature to prevent
particle growth. The templates span 60 and PEG 4000 were used to control the
particle size. The particles were separated from mother liquor by
centrifugation, washed with ethanol, dried and ground and used as additive to base
oil. The particles have H2O and B(3)-O vibrations in their FTIR
spectra. The empirical formula of the nanoparticles was approximately 3ZnO.2B2O3.4H2O
from EDX and TGA analysis. X-ray diffraction diagram indicated the particles
were in amorphous state. When the nanoparticles were added to light neutral oil
the wear scar diameter and friction coefficient was lowered 50% and 20%
respectively.
