The Polysil, made by the firm Nanoprom of Sassuolo, next season it will be used in many areas thanks to a particular process called A.D.N.C (Hard Anodizing, Carbon Nanotubes with ag). This particular process that I will explain below can replace all situations in which hard anodizing is used and in all those components that need to resist friction (Kers, some engine components, gearbox, etc.).

I still do not know if this system will be granted exclusively to a team or if it can be used by those who deem it necessary.

Let's first of all explain what is meant by "Anodic Oxidation of Aluminum Alloys". Due to their low hardness, aluminum alloys have a surface that is extremely vulnerable to scratching and abrasive wear, and they also tend to oxidize spontaneously, also triggering dangerous corrosion phenomena, both widespread and localized (Pitting), for this reason on aluminum bodies. protection is always provided: painting, chrome plating, nickel plating, anodic oxidation, etc. Anodic oxidation is the most congenial and safest protective treatment for aluminum-based alloys among all the others because it is impossible to remove. In fact, the aluminum of the base is transformed, during the galvanic process, into aluminum oxide (Al2O3), generating a protective layer of a very hard ceramic type, refractory to heat and impossible to remove. The crystals of aluminum oxide (Al2O3) have a very hard and compact hexahedral structure with a capillary hole in the center of the hexahedron that penetrates almost to the base of the same. Unfortunately, the porosity of the anodic oxide crystals constitutes a real defect that limits its applications, especially in cases where the surfaces are subject to rubbing or have to work in corrosive environments as the aluminum base comes into contact, through the pores, with the external corrosive environment. The researchers of the Nanoprom Chemical company have studied the possibility of sealing the pores of the crystals of the anodic oxides, by means of a special galvanic process using Ag + ions, thus transforming what was considered a defect, porosity, into a value as these constitute small reservoirs for the Ag + ions, thus being uniformly distributed on the surface and permanently present during their wear. It was then seen that the combination of the anodic oxide layer with the sealing of the pores with Ag + ions gives the "ADNC" coating not only extraordinary antibacterial and anti-mold properties but also other excellent requirements, in particular, if a technological combination is created between the Polysil of Nanoprom and the "ADNC" treatment, we get to have materials that were hitherto unheard of in the industrial world:

- Anticorrosion; - High resistance to abrasive wear; - Antistatic, non-stick and smoothness; - High thermal conductivity and heat dispersion Without forgetting the high hardness and heat refractoriness that are characteristic of anodic oxides. Therefore, the ADNC coating in combination with an appropriate light alloy can be considered, by designers, a real new material and can represent a valid alternative to both expensive materials such as titanium alloys or stainless steels or steels coated with emblazoned coatings. and expensive such as TIN - PVD - CVD - Hard chromium - Chemical nickel - Nickel-Teflon etc.
