Piloto 2: Aluminum surface treatment without Cr
Pilot 2: TRADITIONAL PROTECTION of ALUMINUM alloys uses layers containing HEXAVALENT CHROMIUM, a TOXIC chemical. Due to restrictions in Europe, safer ALTERNATIVES are being sought, such as tartaric-sulfuric and boric-sulfuric ANODIZING, which do not contain chromium. In this project, TWO completely CHROMIUM-FREE METHODS will be developed and optimized: a tartaric-sulfuric anodic layer and conversion coatings, which improve the metal’s corrosion resistance. Additionally, CORROSION INHIBITORS will be tested and methods will be implemented to control the quality of treatments applied to metal parts.
