摘要

The process of generation of nanoceru00c2micas for treatment of surface oxides metu00c1licas using metallic and molu00c9culas self organizu00c1veis.The surface treatment process consists in anchoring the oxides of zirconium and other metals using the pre deposition of molecules self organizu00e1veis (SAM) on different metal surfaces, thus providing greater protection to the corrosion of the base metal and better anchorage Of ink without the presence of toxic metal ions in the process.The process is defined in six stages: 1st 2nd 3rd alkaline degreasing; rinsing; bath containing [San] between 1 and 300 ppm; the fourth bath containing ions such as [Zr ^ + 4 ^] between 0.001 and 1 mol L ^ - 1 ^; 5th rinse.The use of this process to replace the traditional phosphating baths, has the same five stages of traditional process, and does not need special treatment for the water used in the process, i.e. ultra pure water or deionized, and no special temperatures. Is in the process, and the whole process be developed at room temperature.The use of self organizu00e1veis molecules (SAM) provides the deposit of oxides on the metal surface via chemical anchor, thus minimizing the oxidative process of the metal base, in addition to enable the anchorage of paint on the metal surface.
