Oleic acid-modified zinc phosphate nanoparticles with about 15nm particle size were synthesized by chemical deposition method. The tribological properties of the prepared nanoparticles as lubricant oil additives on MSR-10D four-ball tribotest were investigated. Results indicated that the lubricant oils adding oleic acid-modified zinc phosphate nanoparticles exhibited a good friction-reduction and anti-wear property. The zinc phosphate nanoparticle as lubricant oil additive had the optimum concentration. Friction coefficient decreased 14.2% maximally, and the wear-scar width reduced to 36.5% correspondingly, as compared to the base oil without nanoparticles. The results of the worn surface analysis with SEM and AFM showed that the zinc phosphate nanoparticles could deposit on the worn surface and separate the direct contact between the asperities of the worn surface, which was effective in the reduction of the plough and adhesion between asperities.

Over the last years extensively research has been carried out on full or partial substitution of supplies resources coming from renewable resources on traditionally non-renewable, in the case of the automobile sector there are progresses in bio-combustibles (biofuel) and synthetic oils coming from vegetable sources. There are strong efforts to find oil additives which can improve oils features in automobile industry, by adding vegetables oils to commercial lubricant oils, is expected to improve oil thermal stability.  In the present research, different ratios of castor oil (ricinus comunis)-motor oil blends were obtained and their thermal properties were characterized by using the so-called Back and Front Photopyroelectric (BPPE/FPPE) techniques. Several oil-additives concentrations were measured and thermal diffusivities and effusivities as well as densities are reported, getting full thermal characterization for every concentration.
