Objectives
The general objective of the Cr Free REAL project is to develop and test a suitable REACH compliant Cr(VI)-free process for removal of anodic layers. The oxide layers to be removed are deposited either by new Cr(VI)-free alternative processes (SAA, Cr(III) chemical conversion) or by current Cr(VI) containing processes (CAA and Alodine). The oxide stripping process to be developed shall be able to completely and uniformly remove the oxide layers, without deteriorating the aluminium alloy substrate and its properties.




Work packages:
WP1: Project management

WP3: Development and evaluation of an innovative Cr free method on reference alloys
WP4: Identification of the best Cr free solution & implementation on other aluminium alloys & complex parts
WP5: Dissemination, exploitation and communications activities
