Activities
OIL LUBRICANT - NANOADDITIVES:
Generally, the best strategy to reduce friction and wear of materials is to design a scienti鍖c tribological
system, which includes optimized mechanical structures, effective lubricating system, appropriate
matching of sliding pairs, etc .
In recent years, numerous studies have been carried out on the effects of nanoparticles as lubricant
additives on friction and wear.
Generally, most scientific studies concluded that nanoparticles into lubricants are able to chemically and
mechanically modify the sliding materials, producing a protective thin 鍖lm on the crests of surface
roughness, reducing direct contact between the asperities, thus, minimize wear.
TEC STAR is deeply involved in nanocomposite lubricant development and test, finding best nanoparticles
and functionalization treatment to guarantee high and long lasting performances.

In this way it is possible to tune different properties (mechanical, electrical, magnetic, flame resistance, etc.) with filler concentration within the matrix not larger than 2-5% wt. and with no variation of material workability.

This is a nanoparticle-based additive that has been developed for certain specific paint and polymer applications. The product doesnt modify the colour of the polymeric material, it is, if necessary, totally transparent and offers a proven and efficient anti-bacterial effect. This additive could be of interest for all the paint and polymer users and producers, who are interested in providing a strong bactericide behaviour to their products surfaces. It is, thus, possible to have long-lasting clean and healthy surfaces, mainly for those products routinely used by different users: food or commodities distribution equipments, public transportations, etc. Antibacterial Polypropylene.

Then, these nanostructured micro-fillers are directly used within the molten aluminum in order to create the MMNCs. The main characteristic we are trying to improve is the Elastic Modulus of the alloy. In this sense the results are very interesting, as we obtain a Youngs Modulus close to 100 GPa, while, traditionally the value for aluminum is fixed at 70 GPa.
