New layers of conversion anticorrosive properties “Ecologically Friendly”

Substitution of pre-treatment process, (Phosphating), with heavy metal base as (Zn, Ni, Mn) for less pollutant processes, based in the nanotechnology science; that it is the practical of particle deposition of nanometrics dimensions, on surfaces of iron, aluminum and zinc. As consequence of the ecological requirements, are been developed alternative processes that, if in the moment it's not meeting yet, 100% of this “Clamour”, they are going to the meeting of the ecological yearnings. The companies who develop chemical processes of pre-treatments have as objective to develop processes with finer layers of conversion, lesser weight and practically without generation of sub-products or residues. In this way, with these technological innovations, we will be contributing for the preservation of the environment, using more appropriated products and processes.
